Hi bluephoenix66, I admit your problem is really weird, let me just review your issues:
- Netgear DG834N Router
- Desktop/XP can't access FTP and SMTP either wired or wireless
- Laptop/XP can't access FTP only when wireless
- But in general web and other service works fine
based on the above, we could also equate that: FTP doesn't totally work when wireless from the router
yup it can really drive you mad, but kidding aside, I would say thats its a major bug in firmware, hahaha but of course that's just my opinion
have a few questions and suggestions:
1. what's the firmware of your router? have you tried updating it or even downgrading it if there's any new, previous, or beta firmware available?
2. as for the wireless, have you tried it with or w/o wireless security? mixed BGN or pure BG or N environment?
3. You did mention about rules, have you tried setting rules, I assume these are router access rules, have you tried, just for the purpose isolating, to set a pc to allow all inbound outbound access?
4. Have you tried playing with the router settings other than the rules? like disabling additional security on the router, er. SPI, IDS etc., checking other sets like blocked sites or ports, access sched, forwarding/triggering aka services if any, setting a PC to DMZ, playing around with the QoS, UPnP, if any?
5. enabling and checking the logs? for possible clues or info that might help the netgear guys to make their investigation faster.
and perhaps try to give those netgear guys a wake-up call, just to stir things up.
regards,
