Thanks for answer, unfortunately ASA5520 does not do GRE tunnels so no solution there

Yes, ASA not support GRE originated or terminated on itself but can encrypt/decrypt pass-through GRE traffic.

The link I posted is example of a workaround, you can see GRE originated and terminated on two IOS routers behind PIX. The bad side of this solution is you have to involve other devices not just ASA itself.
