How to use VPN and Internet at the same time?

Asked by etereo

I just successfully configured a VPN connection, but after that I can no longer browse the Internet.

In XP I remember that I could do this by unchecking "Use default gateway on remote network" in the configuration of the VPN.

So I went to configure the VPN connection and in the "Routing" tab, checked the "Only use VPN connection for these addresses" and typed the subnet I want (ie 172.36.16.0/24).

Now that seems to work, a little, since I can use pidgin or skype while connected to the VPN, but I cannot ping sites from the terminal (like www.google.com or other new ones). I guess this has to with the DNS server, since sites/apps that already know the DNS resolution can access the Internet, but I cannot access new/unknown IP addresses.

Any help will be greatly appreciated.

Figured it out, work around only. This functionality is prevented by a bug in network-manager (#37239).

In the "PPP Options" tab of the "Edit VPN Connection" you need to uncheck "Use peer DNS" if your VPN doesn't have a DNS server, like mine. This should leave the DNS you had been using before; however, the bug blanks out /etc/resolv.conf so you are left with no DNS, and thus can't reach any new sites.

I made a spript which "restores" a correct copy of /etc/resolv.conf after the VPN connects.

Waiting for a proper fix
