From time to time my wife and I use our Macbooks from WiFi networks that I wouldn't consider secure. Or, in my case, I regurlarly access the internet through a WiFi that blocks some ports that I need access too. Therefore, I've setup a VPN through the Lion server I have working at home. So far, things have been pretty easy. I can connect from the MacBook or my iPhone with no issues. But, I can't use that to actually surf the internet. The network configuration is: Comcast cable mode -> Airport Express -> Lion server. I've got a few Ethernet switches I'm using for the cables that are run to various places in my house. DHCP, NAT and the firewall are all handled by the Airport Extreme. Local network services are all available when I connect through the VPN, ie. I can ping my service, access my NAS, printer, etc.. But, when I try to access anything on the internet the request just times out. So, if I try to access Google.com, it times out. If I try to ping a known good IP address on a remote server, it just times out. The requests are not making it out of the network for some reason. So, what aspect of the network config am I missing? Please don't tell me I have to use the DHCP server in Lion, lol... Thanks for the help.
