Hey Everyone,

Had a little question with VPN routing. A buddy of mine set up a VPN router so that we can share files. When I connect, it seems like all my other internet connections start routing through the VPN. For instance, Trillian disconnects and reconnects itself, I can't access the mail server on campus anymore, and the internet connection reduces to DSL speeds (his connection) as opposed to T1 speeds (my connection). Is there a way to tell applications which interface to use (network or VPN)? Or when connected to the VPN, will all connections route through it?

Also, what's a good setup for name resolution on VPN connected networks? My little network has a DNS/WINS server for my domain. His doesn't have any resolution as of yet. We can access eachother's systems via IP only right now.

Finally, right now I just have one computer connecting to his network. I'm working on setting up the same router on my little network, and then those will stay connected. From the information I've seen, with this configuration, regular internet traffic (trillian, exchange e-mail, HTTP, etc) from each end should route as normally through their own networks to the internet, and then only internetnetwork traffic will go over the VPN. Does this sound right?

Thanx in advance,
Jazzman

How are you connecting to the VPN server? Using a client?

If it is the Microsoft client there is an option under the properties of the site setup where you use the remote gateway as your default gateway when connected.

Disable this and you will use your normal default gateway thus creating Split tunneling.

Some clients don't allow you to enable split tunneling (going over two differnt paths depending on what traffic and destination you are using) so you may not be able to do it.
