[Bug 396387] [NEW] Unable to resolve VPN names AND connect to the Internet

[Eeqmcsq]

Public bug reported:

Binary package hint: network-manager-vpnc

1) I am running Ubuntu Jaunty 9.04 (upgraded from Ubuntu Intrepid 8.10)
2) Version for network-manager-vpnc: 0.7.1~rc4.20090316+bzr21-0ubuntu2
3) When I use VPN on my home PC to connect to my work LAN, I expected to be able to resolve my work PC's name and surf the Internet normally. This was the existing behavior in Intrepid 8.10.
4) When I connect to my work LAN via VPN, my home PC could not simultaneously surf the Internet. I could resolve my work PC's name and I could ping my work PC's IP address.

I found a solution where I should edit my VPN connection -> IPv4
Settings tab -> Routes -> check "Use this connection only for resources
on its network". When I did so, I was able to surf the Internet, but I
could NOT resolve my work PC's name. Pinging my work PC's IP address was
still OK. Summary:

"Use this connection only for resources on its network" is unchecked:
- nslookup my_work_pc (this took a few moments, but it correctly returned my work pc's IP)
- ping my.work.pc.IP (this worked correctly)
- ping 74.125.127.99 (this is google's IP address. this FAILED)

"Use this connection only for resources on its network" is checked:
- nslookup my_work_pc (this FAILED. ** server can't find my_work_pc)
- ping my.work.pc.IP (this worked correctly)
- ping 74.125.127.99 (this worked correctly)

Other info: 
- My vpn type is "Cisco Compatible VPN (vpnc)"
