Single SSL website not working

A user on our corporate network is trying to connect to an SSL website that refuses to work. I can connect to it from my home computer, and I can connect to it if I plug directly into the modem (and get a public IP), but once I go behind our Linksys WRT54G, I can no longer connect to the site. Other normal SSL websites work, just not this one.

Its a simple linksys router, and I've never dealt with this website so theres no way its been blocked manually on the router. I'm using the same router at home and the site works fine. The one difference is at work we're using a less popular internal IP (NAT) as in 172.25.200.x, where as at home, the computer is 192.168.1.x. Is it possible that their firewall is blocking connections from a different NAT IP ranges? I'm guessing the internal (NAT) IP's are bundled inside the packet, so a SPI box on the other end could refuse the connection.

Any ideas on whats going on?
 
Any internal IPs should be stripped from the packet and replaced by the external address and a random return port so they shouldn't have any affect on Internet access. I've seen really dumb custom apps embed IP addresses in their own transactions which breaks many things, but not normal web browsing.
 
I'd make sure the linksys didn't pick up a bad DNS entry. Ping the website, get the IP on both scenarios to make sure they are the same.
 
The problem is definitely there in Linksys router . You should update the latest firmware version of the modem. Add the site as your favorite and then try to open. I think your problem will be solved.

Yep, sounds like layer3 is good (correctly pinging by name). Move up to layer4.

Also really dumb question but check proxy settings on browser just to get that out of the way.

No proxies in use here. 'Automatically check for proxies' is disabled as well.

I gave up on it yesterday, then tried telnet this morning and it connected, so I tried a browser and it also worked fine. Must have resolved itself magically over night.. Or the admin on the other end fixed the problem.. who knows.

Thanks for the help.... I guess 😀
