PPTP VPN connects but cannot ping anything outside network

Suse 11.1 no update, KVpnc 0.9.0

I establish a PPTP vpn connection to my office and can ping and connect to servers in my office(10.37.xx.xx). Once this vpn connection is established I can’t ping out side my network, like yahoo.com. I had to check “Get DNS server from peer” or use “Use specified DNS server” and give it my office DNS server nameserver to be able to see anything inside my network. I believe this is some kind of route problem but my searching and playing for the last two days has not yielded much.

I’ve tried things like setting up a default gateway, hard coding DNS server ip’s for my local provider, and tried my hand at adding routes. What should I try next? Route tables below it you think that is where my problem is.

Before vpn connection, things work
