Hello GrandMasters!!!
I am newby here.
please consider my question as a HELP!!

3 Static CAT-6, 1 Dynamic CAT-6 connect with a Switch, Finaly Swtich Connect with the PC.

here is my problem:

I have 3 Static IP Based Device-

  1. 192.168.127.102
  2. 192.168.0.103
  3. 192.168.0.104

I have my Indoor Internet with WiMAX Connection which has the DYNAMIC connection.

I have 1 Dynamic IP based Device-
1. Internet Connection (Dynamic!!!)

The Last device I have is-
1. 8-Port TP-LINK Switch.

Now, I want to connect all of them in Switch.
Then I want to connect Switch to my PC (for using all the device in one PC).

In my PC I have Only One LAN card.

NOW!!!! here is the problem.....

I want to stay Connected with Internet through WiMAX (dynamic) Connection.
Also, besides, I want to work with my 3 Other Devices (Static).

All of them Must have to Be Used IN MY WINDOWS PC.

Because, Seperatly All of them are Working. With my pc I want to Monitor Them, what are they doing.

Please let me know, HOW CAN I Assamble the IP address in my LAN IP settings.

I am using-
Windows XP SP3
2GB DDR2 RAM
1GbPS Built-In LAN

Short diagnosis and the simple fix (what to change first)
As pointed toward a router, the missing piece is that every device you want the PC to see must share the router’s LAN network — or the PC must be given a route into the other networks. The reason your TP‑Link gave you internet but not access to the static devices is almost always a subnet mismatch (the devices stay on a different address range than the router/PC), a DHCP conflict, or the devices are plugged to the wrong side (WAN vs LAN).

Step‑by‑step, easiest and most reliable setup

  1. Put the WiMAX modem into the router’s WAN port.
  2. Choose one private LAN subnet for everything (example: use 10.0.0.1/24 on the router). Enable the router’s DHCP and set a safe DHCP pool (for example 10.0.0.100–10.0.0.199).
  3. Connect the switch to a LAN port and plug the PC and the static devices into the switch.
  4. Give each static device an address inside the router’s LAN but outside the DHCP pool (for example 10.0.0.11, .12, .13). Use the same subnet mask as the router (a /24) and set the router LAN IP (for example 10.0.0.1) as gateway only if the device needs internet. Do not leave two devices with the same IP.

Quick checks and commands (Windows XP)

  • On the PC run: 
    ipconfig /all
ping <device-IP>
arp -a
route print
  • On the router check the LAN IP, DHCP pool, and the “attached clients” list. Make sure no other DHCP server is active on the switch or on any device.

If you cannot change the static device IPs
Either add a second NIC to the PC and put that NIC on the devices’ subnet, or use a router that supports multiple LANs/VLANs with static routes between them. That preserves internet on WAN while allowing the PC to see devices in their original networks.

Checklist before calling it done

  • WAN is WiMAX, LAN is your chosen subnet; switch on LAN ports; no duplicate IPs; DHCP pool excludes your static addresses; PC firewall not blocking local pings. Following these steps will let one NIC on your PC monitor all local static devices while keeping the WiMAX internet active.

Hello,
What you need is a router instead of a switch. A simple 4 port router will have a WAN connection that you can connect to the WiMAX and 4 LAN ports that you can connect everything else to. You can then put the other static devices on the LAN ports and work from there and if you ever need it you could get the other three systems to the internet.

If I remember correctly the WiMAX uses 192.168.15.X for the subnet it is assigning IP in. If you moved your static devices to the 192.168.15.X subnet with a netmask of 255.255.255.0 with no gateway assigned and let your computer get the dynamic IP from the WIMAX or a new router you would be able to talk just fine.

Thank Your For the post Sir, I really appreciate it.

But i can't setup the ip address..
i used one TP-Link 8-port router.

WAN port = Dynamic IP (Internet Connection)

LAN 1 = PC
LAN 2 = Static Device IP
LAN 3 = Static Device IP
LAN 4 = Static Device IP

in my windows TCP/IP settings i make like this

192.168.2.x
255.255.255.0

gateway = blank

nothin happend
no internet, no static device.

then i change them to AUTO Obtaining IP,
Now, I have the Internet but NO STATIC IP!!

Please, Sir, let me know how to use them.

ALL IP ADDRESS I PROVIDE is an EXAMPLE....
just make like that settings which i mentioned above.

please give me an Step by Step Instructions.

regards

Hello,

A router and a switch are not the same thing. A router will have settings where you can set up DHCP and a WAN port and several LAN ports and can use NAT (Network Address Transation) top give multiple private IPs fot a single public IP. A switch is simply a jusction box that allow the systems to connect and does not do much else.

I use a router at home that my internet modem is connected to. The cable modem goes to the WAN port and receives a single dynamic (DHCP) address from my service provider. In the router I have DHCP set up to provide addresses over the LAN ports and the router uses 192.168.2.1 and is the gateway for my LAN. My Linux server is at 192.168.2.100 and the WIndows Server is at 192.168.2.101 both with a netmak of 255.255.255.0. DHCP is running on the route for the LAN and uses addresses 192.168.2.2-192.168.2.99 NM 255.255.255.0.
