Is there a way to setup a VPN tunnel from a PIX to a Checkpoint Firewall (with its external interface running with a private IP address) behind a F5 BigIP that is NATing a Public IP address to the private IP address.
When debuging I get the following error message:
crypto_isakmp_process_block:src:152.200.x.x, dest: 129.41.x.x spt:500 dpt:500
