Could I ask you to: (1) Confirm the problem still exists, especially if you've moved forward to a more recent rev of FreeBSD. (2) Let me know a bit more about your firewall/ipsec/etc setup. In particular, if you can easily identify a minimalist setup to reproduce this problem. Do the packets you're describing enter via a tunnel, or do they arrive unencapsulated? (3) Send me tcpdump output that shows the packet ingress and resulting ICMP. Thanks, Robert http://www.freebsd.org/cgi/query-pr.cgi?pr=112722
