Hello - I have recently had a WRVS4400N installed between my home network and Comcast modem as a requirement for a home control system. I have used many modems and routers in the past, and never had trouble configuring it to allow remote desktop access to and from the local PC. Nothing I do with this router, though, seems to work. Even simple things do not work. I can use the router's Diagnostic page to ping common sites (like Google) and it works fine. Trying the same from the command prompt on the local PC receives no response. Tried shutting off the firewall in the router and no help. Running W7 with McAfee, and turning off the PC firewall in McAfee also does not help. Have reviewed the manual extensively and have also come up with a blank. Can someone tell me what I am missing? Thanks in advance.
