Can't Access Internet

[Ken]

I have been following the Group Policy video and have set up my two servers with AD. The problem I am having is that neither server can now access the internet. I can access each of the servers from each other as well as from any of the workstations so everythings appears normal except for internet access. When attempting to repair the connection, I was receiving a message that the ARP Cache could not be cleared. I did find info that had me shut down the Routing and Remote Access, still had no internet. I then added back in my default gateway which then restored the internet access.

Now my two question... 1. Should I leave the Routing and Remote Access disabled and 2. Should I keep my default gateway (192.168.1.1) or should it remain blank as in the video?

Any assistance would be deeply appreciated.
