Working IPSEC in 2.15 not working in 2.2

[STI2011]

Hi,
yesterday I have converted my well running 2.15 to 2.2. After restarting everything is working fine except a fixed ipsec tunnel.

It's starting the tunnel but seems not to complete it.

Log from other side (Clavister SG):

IPSEC: id=01802703 rev=1 event=ike_sa_negotiation_completed action=ike_sa_completed local_peer="x.x.x.x ID x.x.x.x" remote_peer="y.y.y.y:13856 ID y.y.y.y" initiator_spi="ad3baeb7 a71971b7" responder_spi="006a2cbb a6f22e46" int_severity=6 

pfsense log:

Ipsec-Status from the gui says 'established' and SPDs are there. The other side shows the tunnel down.

Anything I can do?

Greetings

That is something blocking the connection from happening?
Firewall rules maybe?

Both sides firewall logs are ok. I have inspected all logs, tried to use different interfaces, but always with the same result. The value in the interface field seems to be ignored…

Status -> Ipsec shows the tunnle up, Dashboard -> ipsec -> tunnels shows phase 2 down.

Also after yesterdays snapshot, i wasn't able to ping connected openvpn clients any more from the lan. ping from pfsense was still possible.

After switching back to 2.15 with the same config everything was working...
