Hi, I have the same problem described here:
http://openbsd-archive.7691.n7.nabble.com/pfsync-over-ipsec-is-broken-td257496.html#a257681 My system is 5.7 i386 I have keep state (no-sync) on all local terminated traffic (including ipsec udp/esp) and set skip on enc in pf.conf. I can see only outgoing PFSync traffic (no incoming) with increasing replayed packets received on both firewalls. netstat -p esp -s | grep replay 304 possibly replayed packets received Does anyone have working PFSync over IPsec Setup?
