Site-to-site VPN between two ASAs, one does not encrypt traffic
I have a site-to-site VPN established between two ASA firewalls. It was working fine for a while now, however VPN was brought down due to some other outage in the network. Now the VPN comes back up (both phases established), but I do NOT see "encaps", encrypts" on one ASA. That means one of the ASAs is not encrypting traffic, and so it gets dropped. I dont even see any hits on the crypto ACL of this ASA.
I have made sure that the inside traffic is not NATed and I have a route to remote network thorugh the interface where crypto is applied.
Does any one have any suggestions of how to debug/resolve this issue?
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
