Is it possible to test VPN while connected behind the router?
Posted on 2009-02-18
not sure if I'm trying to test something here that isn't possible, but I have a snapgear SG560 firewall router. I have setup VPN access (setup a PPTP VPN server and PPTP VPN client) and am trying to test it by connecting through a macbook (os x 10.5.6). So to make it clear, I'm behind the firewall, connected to the local area network. I'm trying to test it locally (if possible) before I head out and try and connect outside of the firewall.
The mac tells me I'm authenticated/connected, however I can't get any web pages up when trying to navigate to anything in a browser. Is this because I am behind the firewall and wont work? Entering an IP address doesn't work either (for example, 184.108.40.206 which is Google's IP address)
Also, I have an iPhone and I setup an L2TP VPN server/client on the router. Via the iphone I can VPN into the router (authenticate and connect) doing it via 3G (i.e. not connected to the local wireless point). I can connect to my servers behind the firewall (for example 192.168.0.10 which is one of my IIS servers works) but trying to resolve a domain name (like google.com) doesn't work. Instead I have to use the domain's IP address (for example, 220.127.116.11 works and brings up the google website).
