    Bala, L2TP is the most secure tunnelling protocol. I believe though that if you are just using the Cisco VPN for LAN to LAN, ipsec may be the best bet. It will authenticate against the other VPN server and allows for excrypted data transfer. You'll want to configure "Tunnel" mode for the most secure VPN. Terrence

    I have to agree with the last post that IPSEC is going to be your best bet for point to point tunneling between two Cisco devices, particularly if one is a 3000 series Concentrator and one is a router or a PIX. Triple DES is nothing to sneeze at, and is quite secure for most requirements.
