https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248474 Andrey V. Elsukov <ae@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kp@freebsd.org --- Comment #9 from Andrey V. Elsukov <ae@FreeBSD.org> --- (In reply to Michael Muenz from comment #8) AFAIK, pf NAT and route-to rules work as last point in the network stack, i= .e. pf doesn't reinject packet back to the stack and there is no way for IPsec = to catch the packet to make IPsec transformation. If you want to make it works, you need to patch pf(4) and add IPSEC_OUTPUT()/IPSEC_FORWARD() methods to s= ome points, where pf does send to the network interface like IP output routines= do. Probably some changes also are required in the inbound path. I don't think that proposed for strongswan change will help. --=20 You are receiving this mail because: You are the assignee for the bug.=
