Hi, We have a home network with 3 computers (different OS on each) behind a router. (with no firewall installed). About a month ago we bought a new (generic) router. And about two weeks ago, suddenly, no one accessing the internet from behind the router could access a particular website (craigslist.org). AFAIK everything else gets through. The website is up and running. When one computer is connected directly to the cable modem they can acceess the site. So I suspect it is the router. I called the router support and they were NO help. Admittedly this is a REALLY weird problem. I have never encountered such a thing. I adjusted several online settings for the router but no luck. Unplugged the modem, reset/restarted the router.. nothing. Oh yeah its not a secure site and I checked the "HOST" file and its not listed. Does anyone have any ideas how to fix this?

Cycling the router does not necessarily correct NAT routing table errors. The best way to fix this is to "reflash" the router BIOS with the latest BIOS drivers. You can usually d/l these from the company's website along with installation instructions.

Thanks for the reply, the router is a CompUSA model which is made by Gigafast. Anyway, I went to the CompUSA site d/l updated firmware, installed it, restarted and I thought for sure that would do it, but unfortunately we still cannot access that particular website. Was what I did "reflashing the bios drivers" in the router? any other suggestions? Thanks again.

Try disabling the routers FireWall as a test. Some older sites require some sort of response to a request to the Clients ID port 113. If your router stealth's this port instead of responding Closed, some sites will not initialize a session with the requesting Client. Most routers stealth all ports but this one. Some have an option that allow you to stealth it also, or allow it to report Closed status to requests. Some newer routers, based on the way software firewalls handle this, may try to stealth this port to port probes, but respond Closed to IP addresses that you have tried to contact. This suggests that your IP address my be experiencing a port probe or scan from some virus infected machine on the Internet. You need to setup and take a look at a firewall log to see if this is happening and confusing the new router.
