Hi, recently i noticed the following problem with my Linksys Routers: I'm unable to block inbound tcp ports 1863 and 5190 on WRT54GL (using the latest DD-WRT firmware) and also on BEFVP41 (1.01.05) and RV082 (v. 22.214.171.124). On all three devices nmap (4.03) shows these ports as open and i'm able to telnet trough them (althought disconnected almost immediately). All firewalls are turned on, all UPnP functions are disabled and no MSN/ICQ clients are behind the routers. I noticed other users with the same problem and without any solutions... So i'm forwarding the ports to non-existent local IPs, but i want to know the source of the issue if any... Any help will be great.
