We're attempting to get XTP traffic to traverse a VPN tunnel between 2 ASA firewalls running 7.2.3 code. The traceroutes show that the traffic gets to the firewalls but does not get through the VPN tunnel. What options should be set on the firewalls to transport XTP (IP Protocol 36) through the VPN tunnel?
Attached is a copy of the config from one of the ASA's. The other ASA is the mirror.
The VPN tunnel works fine for IP traffic, but when we attempt an XTP traceroute it completely dies at the ASA's and does not go through. Any ideas?
First check if the traffic is able to go through the first ASA by checking the hit counter of crypto ACL. Then check if the traffic if getting encrypted using command "sh crypto ipsec". Do the same at the receiving end also.
