IPSec lan-to-lan doesn't work after PfSense upgrade to 2.2

[JoelLinn]

To come back to the problem, if the tunnel is up but no traffic is coming through, can you further specify it?
Is there only some traffic (like small ping packets) that get through or is it nothing at all.
Because I experience a problem where fragmented packets get lost. https://forum.pfsense.org/index.php?topic=87610.0
Maybe you want to perform similar analysis to confirm that your current problem is similar or not.
