IKEv2 VPN between OPNsense and Check Point


Anyone here with successful IKEv2 IPSec tunnel between OPNsense and Check Point?  If I'm not wrong OPNsense runs some variant of *swan IPsec (strongSwan?).

I'm trying to connect OPNsense box running the latest 21.7.3 with Check Point R77.30 without any luck. The tunnel seems to establish fine -- no errors on both sides and they both agree on encryption parameters and encryption domains but I can't see any traffic arriving via the tunnel on the destination server at the Check Point site.

I have no issues whatsoever with IKEv1 -- the tunnel works without any problems with the same parameters.

There is nothing special in terms of configuration: both Phase 1 and 2 are AES-256/SHA1/Group2.VPN

Any hints would be greatly appreciated.
