I just upgraded my WRT54G v2.2 to the latest Linksys firmware which is v4.20.6. For some reason, port 80 is open to the outside world and I've tried everything I can within the software to disable access from the outside. The "Remote Router Access" is disabled and I also disabled the "Wireless Access Web" (whatever that does) and port 80 is still not closed. I don't have any computer in the DMZ and I don't have port 80 forwarded to any specific machine. Any ideas? Was it always like this and I just now noticed?
