Hi all,

I compared three of the various ways to set up an IPsec connection and have a little difficulty to see the details:

1. Build a GRE tunnel (interface), then define GRE traffic as interesting in the CryptoACL, build the according CryptoMap.

2. Build a GRE tunnel (interface) and apply a CryptoProfile. Tunnel Mode is GRE.

3. Build a tunnel (interface) and set the mode the ipsec. Apply an CryptoProfile.

Are these just different versions to do the same thing ? If not, what are the little differences ?

Thanks in advance,

Oliver
