I guess one of the nice utility often forgotten that comes with Cisco VPN Client is SetMTU. It is installed with the client and you can find it at;
StartMenu->Programs->Cisco VPN Client->SetMTU
So it is a peaceful life and don’t have go through the GUid in registry finding out which adaptor you want to set it
Oh yEAH! Using CVPN Client on Microsoft XP ? Don’t forget to get the latest version, 4.8 which is the stable one and you can download it from Cisco Site.
