I have a E4200 V1 router. A website that I have been accessing for years all the sudden no longer works. If I use my PC and PPTP VPN to another location, I can browse the website fine. If I remove the router and plug directly into my Comcast internet connection, I can browse the website fine. If I enable logging on the router, it shows the connection on port 80 just like every other outgoing connection. Security log shows nothing. I was on firmware version 1.0.03, upgraded to 1.0.05. Tried resetting to factory defaults before I updated firmware, and after I updated the firmware. The website all the sudden just stopped working 2 weeks ago. I also tried putting my PC as the DMZ IP address and nothing.
I was sure it was my Comcast Cable internet connection until I bypassed the router and no longer had the issue. Any assistance would be greatly appreciated.
