I noticed that IPv4 networking just suddenly stopped. Debugging with tcpdump on my external interface shows that pf NAT isn't taking place. My internal (non-routable) IPv4 addresses are being put on the wire to my ISP. Things were just fine.
/etc/rc.d/pf stop followed by /etc/rc.d/pf start clears the condition.
My IPv6 (via tunnel broker, gif0 on $ext_if) works. I can use IPv4 from the FreeBSD 8.2 machine itself. Only the boxes on the IPv4 subnet(s) (all need NAT) show problems. These same systems can use IPv6 to the 'net just fine.
Is there anything I can start looking at to see what is going on?
