I'm new to the forums, and I am having a hell of a time getting a successful VPN connection from my school to my home.
My home is set up like this: I have a linksys e2500 router, a computer (not the VPN server) is connected by Ethernet cord from the router. My windows XP computer, a Dell Dimension 4550 desktop, is connected by a wireless adapter to said router. This computer is what I am using as the VPN server. I am using this computer, which has no way to be directly wired to my modem for internet access, because it is always on, and it only makes sense to have this as the server.
I have a VPN correctly configured on the Dell computer. I am able to connect FROM this computer TO a VPN server set up from my laptop (Windows 7 Ultimate), but I am unable to connect from my laptop to the home desktop. I get the error 800 code.
However, I am able to connect from my laptop to my home VPN server only while connected to the same internet. When I was able to do this I thought that I had everything set up correctly only to find out when I got to school that it did not work. Although I am still able to connect to my laptop VPN from my home computer while I am at school.
Both computers use Norton 360. I have tried to disable the smart firewall, still unable to connect. I have unblocked stealth ports, still unable to connect. I even set up a firewall rule for ports 1723, 500, and 1701, and I'm still unable to connect.
I am pretty sure that I have everything set up correctly as far as my router goes. I have VPN passthrough allowed. I have set rules in the 'Port Range Forwarding" Port 500, Port 500, port 47, and port 1723.
I have used the PortQuery program to check ports. If I use the home computer to check ports on my laptop, everything is successful. But from my laptop to my home computer, I usually get "Not Listening" or "Filtered."
