Did any of our suggestions help you?

My experience is that AT&T fiber for residential use does allow servers and does not block ports. I used to have Verizon FiOS which, also, did not block ports, but that was a business account and so under different rules. Spectrum and Optimum Online business accounts also didn’t block, but I paid an extra $10/month for a static IP back then as well.

It might be the router that is blocking. Most routers these days block port 80 by default. This might be the router built into your cable modem as well.

Many if not most ISPs block port 80. More at https://www.google.com/search?&q=port+80+inbound+blocked+by+ISP

This has been my finding for over a decade.

You're a little thin on details about "my network" but for the purposes of this discussion I'm going to assume you are talking about a typical home network comprising of a Router and a bunch of devices connected to it.

Let's think about the network route required to get from one computer on your network to another, and this is what I expect is happening when you say "works locally". The router knows about every device on its network and knows how to route traffic to each.

Computer A --> Router --> Computer B

Now let's consider what I propose could be happening when you make the same request using your DDNS service. There are two scenarios that come to mind:

Computer A --> Router --> ISP --> DDNS Service --> ??
Computer A --> Router --> ISP --> DDNS Service --> ISP --> Router --> ??

In both scenarios your request leaves your network via your Router and your ISP and arrives at the DDNS Service.

In the first scenario, you have the wrong IP configured with your DDNS Service so the request goes to the wrong place from there.

In the second scenario, the request makes it back to your Router but the router doesn't know where to forward it on to. In this case you will need to configure Port Forwarding on your router. What Port Forwarding does is tell the router "when you receive a request for port x, please forward it to this IP and …

DDNS is configured correctly and the hostname works locally, but I can’t access it from outside my network. Remote management is enabled and set to port 80. Any idea what I might be missing?

Do you have a question?

For connecting dlink extender to wifi​, plug the extender in near your router. Connect your device to the extender's WiFi network. Open a browser and type dlinkap. local or 192.168.0.50. Follow the setup wizard to connect it to your router's network. You can also use the WPS button on both devices.

Hey! Just try giving your router and PC a quick restart, update your WiFi driver, turn off that power-saving thing on the WiFi adapter, forget the network and join back in, then run the troubleshooter. If it’s still acting up, just drop the error and your device info here!

the issue may be due to no signel Solve the no signal issue and this isue will be solved automatically.

The wifi connectivety issue can be due to no signeal problem. Take a look and check that why signals are comming slow. When you solve the signel issue, the wifi connectivity automatically become good

Please help me come up with a compelling argument to convince my husband to spend an additional $200/month on AT&T Fiber Internet with 5Gbps download / 5 Gbps upload.

It turns out we were able to work with Xfinity's retention team so that the TV plan ended up costing less than we were expecting. We're paying only $100/month more than we were. Considering switching down to 2 Gbps fiber which would pretty much break even on pricing.

First post from my new (~2 minutes old) 5Gbps fiber connection. :)

Had a similar experience with Bell. They wanted me to pay for them to fix a problem with major static on my phone line. Instead I switched to Shaw for internet, TV and phone and have had great service with them ever since. I've had Bell come to my door a few times to get me to switch back and I told them every time no because their customer service is shit.

Soooo ... looks like we're getting AT&T Fiber installed this Saturday.

To make a long story short, very shortly after I posted this topic, we began repeatedly having issues with Xfinity service going in and out. Every time we went to report an outage, Xfinity either completely denied that there was an outage and wouldn't let us report it (since it was intermittent and constantly going in and out, so while it was unusable from our end, they were still able to ping our modem), blamed our cable modem/router when meanwhile our TV was out as well, or suddenly had planned maintenance windows. After 2 weeks, they finally acknowledged there was a bigger issue, had another planned maintenance window, and gave us credit for the past 2 weeks of headache. The next day, we had yet another outage. My husband fought with them to get a technician appointment, and when it eventually came around, the tech gave a 15 minutes heads up, and then never showed and ghosted us. My husband then fought to get a second technician appointment, which was supposed to happen yesterday, but they rescheduled (without letting us know) for today. My husband literally told the guy at the door just a few minutes ago, "You were supposed to be here yesterday. No one ever showed up for the appointment. We signed up for AT&T." They're now at the pole trying to see if they can repair our service anyways. Anyways, that's my very long rant.

I hadn't considered that you could host Daniweb from your home. That would certainly make it more convenient.

While it might technically be possible to host DaniWeb from my home, it would not be practical. Firstly, I did some research since yesterday, and it seems against the AT&T terms of service to have servers for a for-profit business running from a home plan. A small blog would fall under the radar, but they would likely shut us down for the amount of traffic that we get.

Secondly, we currently have a rack at a datacenter in Texas. We would need to ship all of our equipment to my home, and then find room in our small home for a server rack.

Thirdly, we would lose the advantage(s) of being in a big datacenter. Redundant uplink connections, etc. The datacenter is also minutes from where blud, our sysadmin of 20 years, lives, so that if anything were to go wrong, he could go there in person and fix it.

We also have the problem of very frequent blackouts where we live, that typically last 2-3 days at a time. After dealing with it for 2 years in a row since moving here, on the 3rd year, we finally installed solar last year. After spending so much money on a solar array and batteries, there has been only one blackout since, lasting for all of 12 minutes. (Of course, right?)

So, all in all, not very practical or realistic to …

I hadn't considered that you could host Daniweb from your home. That would certainly make it more convenient. Would the savings from not having to pay a company to host Daniweb be the same or more than the upgrade and additional power costs for the home servers?

Dunno - could you run Daniweb at home with that kind of bandwidth and save a chunk on data centre fees?

Or would something like that fall foul of the Terms of Service and/or Acceptable Use Policy?

Running servers is allowable. Whether or not the servers can be for business purposes with a home plan, I have not yet looked into. Whether or not 5Gbps is enough, I also don't know, although my first guess would be that it previously wouldn't have been, but it would be with the very little traffic we get today. However, I also wouldn't be able to speak to the reliability of a home Internet plan, fiber or otherwise. In the datacenter, we are directly connected to the Internet through multiple bandwidth providers.

Even more reason for caution, if your livelihood depends on a stable and reliable connection.

More than anything, my livelihood depends on the ability to get out of bed, which is a real struggle most days. Hence the lack of a viable livelihood these days.

Sounds like you want it because you want it and can't think of a reason to justify it.

Yup. That one!

Can you think of any ways in which it would make your life easier?

No. Can you?

How much time would it actually save you and how often would it make a noticeable difference?

That one's easy. It would make a very noticible difference every time …

Awaiting suggestions.

Sounds like you want it because you want it and can't think of a reason to justify it. Can you think of any ways in which it would make your life easier? How much time would it actually save you and how often would it make a noticeable difference? Advertised speed is often much greater than actual speed. As you are well aware you are often limited to the speed at which the server you are connecting to can send the data, and that also depends on the current load on the server.

This is a very old thread, but I feel the need to clarify that it is definitely not plain text.

And you need 5Gbps because...?

Awaiting suggestions.

And you need 5Gbps because...?

AT&T just became in our neighborhood available and I'd love to go back to it.

Yeah, I'd be letting the neighbours be the guinea pigs. I have little doubt that the "it's available" came from AT&T marketing department as soon as someone in provisioning said "um, maybe". Even if they really are "ready", if there's an initial stampede of early switchers, you might be in a queue.

Even more reason for caution, if your livelihood depends on a stable and reliable connection.

On the plus side, at least you now have a stick to beat your existing provider with.

In NY, I had Spectrum cable at home, and Verizon FiOS fiber at my office.

In CA, I started with Xfinity cable. Just before COVID, we moved into a townhouse that had a spotty connection that became unbearably inconsistent. Apple ended up paying for us to have AT&T fiber because my husband is an engineering manager there, and they needed their employees to have reliable Internet connections during work from home orders. We had a really shitty experience with Xfinity customer support and a really excellent experience with AT&T.

We have since moved and AT&T wasn't available, so we went back to Xfinity cable. AT&T just became in our neighborhood available and I'd love to go back to it.

My ATT story. Moved from MA to CA and needed to get the apartment setup. The apartment complex was an ATT only zone.
Fine. Call ATT and their phone system kept routing me to their Massachusetts offices. No one at ATT could override that or forward me to the right office.

OK, find the local ATT store and go in. Much confusion at their counter because their store system was indication my phone number was in MA. (Duh)

Another person in the shop stepped in and took over. Got the work orders placed.

The next arrival was The ATT Keystone Cops episode. The installer showed up and claimed they need to get a phone line working first and then DSL. I had ordered fiber but not the gigabit as well, not available there.

Anyhow the tech calls in and arranges for the DSL/Phone tech to come in.

DSL/Phone tech shows up and tells me the wires are bad. I wait for them to figure it out and they run out to the distribution box and fix the wiring. Hint: It was on a high speed set. OK, the high speed internet tech is queued up.

High speed tech arrives and tells me the wiring is wrong. Since I was there for the DSL/phone tech I ask if what they did had to be undone. Yup they say. They run out to the box and put the apartment on the high speed connection.

Tech unpacks gear, sets it up and done …

Please help me come up with a compelling argument to convince my husband to spend an additional $200/month on AT&T Fiber Internet with 5Gbps download / 5 Gbps upload.

We currently have Comcast Xfinity cable with 1.2Gbps download and something like 35 Mbps upload. Xfinity has a 2Gbps plan we could potentially upgrade to. I'm not willing to cut the cord and get rid of cable TV. That means that we would be keeping a Comcast account just for a TV plan.

Hi rproffitt,

Thanks very much for your response.

I FINALLY got a response from ProofPoint. Apparently DMARC, DKIM, and SPF are not enough. They said "To be considered for delisting, we require that the PTR for an IP needs to be given a fully qualified domain name which resolves back to it." So if you share your IP with more than one website, I do not believe this can be accomplished.

ProofPoint appears to be overly-aggressive. When I get an email from someone that uses ProofPoint, I cannot respond.

I'm not sure where to go from here for a shared IP.

BTW - After filing dozens of times to white-list my IP, I'm now getting unsolicited emails from ProofPoint!

Regards,

Jim

Here are a few things to check:

SMTP Server Details: Ensure you have the correct SMTP server address and port. Double-check the SMTP details for the service you are using (e.g., SMTPmart,SendGrid, SMTPget and Mailgun).

Correct Port: Make sure you're using the correct port for your SMTP server (usually 587 or 465 for SSL/TLS).

Firewall/Antivirus: Check if your firewall or antivirus is blocking the connection to the SMTP server.

Network Issues: Verify that your network connection is stable and that you're not behind a proxy or VPN that could cause issues.

Read https://www.reddit.com/r/proofpoint/comments/1c4v619/how_to_fix_proofpoint_blocking_legitimate_emails/ and see that they had to work with someone at the company to find and fix it. So the answer is yes to the question.

Hi,

Is anyone having issues with ProofPoint blacklisting your IP?

It appears that many organizations are using ProofPoint to screen emails, and my IP somehow became blacklisted.

I filled out their reconsideration form many times, took remedial action (although there was not much to correct) and still weeks later, we're still blacklisted by ProofPoint. When I tried reaching out through my AOL account, that email also bounced.

I'm open to any thoughts and ideas.

Thanks,

Jim

It seems like the issue might be related to network configuration or Windows settings automatically removing the IP address. Try releasing and renewing the IP address using ipconfig /release and ipconfig /renew in the command prompt. Also, check your DHCP settings and make sure your router is properly assigning IPs. If the issue persists, updating network drivers or resetting TCP/IP settings could help resolve it.

The term "A Black Eye for Cloud Computing" likely refers to a setback or issue that has negatively impacted the cloud computing industry, such as data breaches, service outages, or security vulnerabilities. These challenges can damage trust and slow down adoption, but the industry typically rebounds with stronger security measures and improvements.

This is a random reply to the topic.

It is possible that DHCP settings or network adapter configurations may be causing the automatic IP address removal in Windows 8.1. If this is the case, please ensure that your network adapter is configured to obtain an IP address automatically. Update your network drivers or reset your TCP/IP settings.

For fast and reliable text streaming, I recommend HTTP/2. It offers low latency, multiplexing, and efficient data transmission.

QUIC is the preferred transport protocol for quickly and reliably streaming text, optimized for low-latency communication.

Start with some free online courses to get the basics down. Websites like Coursera, edX, and Udemy have beginner-friendly courses on cybersecurity. They’ll give you a solid foundation in concepts like network security, encryption, and threat detection.Get your hands dirty with practical experience. Websites like Hack The Box and TryHackMe offer interactive labs and challenges that simulate real-world hacking scenarios. They’re super fun and great for learning by doing.Consider getting some certifications. The CompTIA Security+ is a good starting point for beginners and is widely recognized in the industry. Once you’re comfortable, you can look into more advanced certifications like CEH or CISSP

For streaming text, the Transmission Control Protocol (TCP) is often used because it is reliable, ensuring that data packets are delivered in order and without loss. However, if speed is more critical than reliability (such as in real-time applications), User Datagram Protocol (UDP) can be used, possibly with custom error-checking and correction mechanisms. For a balance between speed and reliability, QUIC (Quick UDP Internet Connections) is a modern protocol that combines the benefits of both TCP and UDP and is optimized for faster, reliable transport, making it a great choice for streaming applications.

For streaming text, WebSocket is a fast and reliable protocol. It enables real-time, bidirectional communication with low latency, making it ideal for continuous, efficient text streaming and interactive applications.

It's not a job you would get into without your degrees. The usual CompSci degree then back to school for your masters of cyber security engineering and then it might be possible to enter the field of cyber security engineering.

Short answer: Back to school.

Passing familiarity with a search engine would be high on the list of skills.
