Split Tunnel VPN

[unsmashed]

I've got a VPN connection to my work, and it connects and works just fine. However once I'm connected I can only connect to work servers as they don't let the Internet connection pass through.

My understanding is I need a split-tunnel setup to let work traffic go through the VPN (when connected) and other internet traffic to go through my existing internet connection.

I have the IP address ranges of my work systems already. For discussions sake, let's say its:

200.100.120.0
200.100.121.0
200.100.122.0
200.100.123.0

(all 255.255.255.0)

In addition, they have a URL where the Windows client downloads existing VPN routes everytime it connects. Let's say its at http://www.server.com/morevpnroutes.txt.

How would I do this?

Thanks!

I've found a few things since I've made the post.

There seems to be a /etc/ppp/ip-up and /etc/ppp/ip-down script that can be configured - perhaps this is the place to do it.

Would I need to add "/sbin/route" statements?

How?
