Can you ping, traceroute, telnet, ftp into the box from outside the network? try pinging port 80 see if an error or filter statement is generated. I am sure there are more efficient ways to check that... I would suspect that if it is a connection that the ISP would normally not want you having services on... that you might want to take it up with them. Could be a generic filter against port80... I know we are having problems with remote DSL users using corporate mail because Sympatico up here can't police thier own network, and has chosen to filter out all SMTP traffic not destined for thier site... the stupidity of some networks is unreal some times. Could be a similar tpe of generic filter they just put in place hoping that it would curb code red or something... you could try putting apache on a different port(8080 or something totally off-the-wall) and see if it responds... but if they *have* applied filters, they may have everyting except a few key ports filtered out.
