Your problem describes mine to a Tee, except that I am dealing with two computers that are wired to the router. My router is a Linksys WRT54GS, v1.0, with the latest firmware.

The only change I have recently made to my computer was on installing the Cisco VPN client v.5.0.0.1 (??). Thinking that may have created a problem, since it is the first version to work with Windows Vista, I uninstalled it, and then this connected-but-not-communicating problem did not go away.

It is strange that I CAN get a SecureCRT (tcp) connection to machines outside my domain, however.

This is a sufficiently bothersome problem that I would hope you found a solution. Since one has not been posted, I may try to contact you through the Administrator.
