OSX Lion network configuration problems

So i upgraded to lion server and eventually gave up on running my computer setup as a VPN endpoint. I recently noticed that when im not at my home I cannot get a wifi network connection to the internet. The WIFI connects, and any router DHCP automatically assigns an IP address, and DNS servers but i cannot get actual internet connections on a network outside of my home. My locations are set to automatic. can anyone please help?

 

Update

Ok, so i just created a new location in system preferences>network. Now all of the sudden i have access, and none of the settings seemed to change. Why would i have connection issues when my location is set at automatic?
