I have a WRV54G device. I am not using the VPN component. I am simply using it as a Wireless router. I am running Windows XP SP1, not 2. From my workstations, I need to map to a file server on the internet. From 2 other locations outside of this network, everything is fine. From behind the WRV54G, port 445 is being blocked. Based on my testing, I think it is happening in the WRV54G. I am testing my doing "telnet \\x.x.x.x 445" This tells me the port is blocked. This works from other Linksys routers I own, but not the WRV54G. Any ideas? Thanks!
