We use a persistent tunnel for a remote office and have configured TCP inspection to avoid SSH session timeouts:
access-list No_SSH_Timeout extended permit tcp any any eq ssh
match access-list No_SSH_Timeout
set connection timeout idle 0:00:00
I'm having trouble to find the right configuration to do the same thing with IPv6. The class-map seems to demand an extended ACL, but ASA Software 8.4(3) only supports regular IPv6 ACL's, not extended. Is there another way to do this?
