I've upgrade to ASA8.0 SW and now can't create GRE tunnel from inside VPN Rtr to other branch inside Rtr.
Attempt to write NONAT and CRYPTO access-lists with GRE conditions is posible: That's OK!
But applying of cmd:
#nat (inside) 0 access-list NONAT
result in "ERROR: access-list has protocol or port" msg.
I attempted to downgrade to 7.x SW
but ERROR msg are repeated.
How I can create GRE-IPSEC tunnel between two branch routers over ASA-to-ASA crypto tunnel?
