It is best not to use your DC for routing / NAT / Remote Access purposes.
In fact, if you are just using the box as a router or form NAT, it may be
best to have the box be a stand alone server.
To configure the machine as a router you can run RRASMgmt.msc. This is the
RRAS snap-in. Right click on the server name, and select Configure and
Enable Routing and Remote Access. This will take you to the RRAS wizard.
Follow instructions on the wizard and you should be up and running in no
time.
If you have other issues, post back to this forum.
