Comment 2 for bug 278309

I concur. This is a major problem. My desired setup for VPN usage is to tunnel all traffic to specific subnets through the VPN, and all other traffic goes out the normal default gateway for the network. Having the VPN interface forced as the default gateway makes the connection basically unusable. Additionally, there is no way to specify the MTU setting for the ppp interface, which tends to break my connection with any large packets. I usually set my MTU to 1412 and have no problems. With the current configuration I am forced to run a script after connecting to manually change the MTU to 1412 for the ppp0 interface.
