Port of Frustration

I have a web server. Port 80 is blocked (per Shields up test at grc.com).

My router has port 80 forwarded to the correct address.
My firewalls have port 80 in the exclusion list, and besides that....they are all off.

Port 80 is STILL blocked. Where else can I look?

Can you telnet to the web server over port 80 and issue a get?

telnet webserverip 80

This verifies 80 is open and listening.

Is the webserver staticlly assigned?

What kind of router do you have?  What kind of firewalls do you have?
have you tried forward and reverse lookups on the dns name/ip they might be testing a different site.
verify here

also do you have an acl's on the server itself limiting traffic?

have you looked at your router and see if your packet count is going up on the rule allowing the traffic?
Could of course be your ISP blocking external port 80 requests to regular subscribers (home connections). If you have a business-type connection, talk to your ISP helpdesk.
