Well, I did you one better and upgraded the system to 4.7-REL.
Some additional info: from looking at an ethereal trace, I'm seeing source
quenches coming back to the machine VPN'ing in. Interestingly, ethereal also
reports an invalid checksum on a bunch of those packets. The strange thing
is, this machine has acted as a router/NAT for quite a while and so of all
the machines on the network, it's hardware is probably the most stable
(easily 150+ day uptimes).
Any ideas?
Thanks for your help so far,
Leonard

That doesn't look so good. But it doesn't look "crazy" from the
netgraph side, just like a lot of packets are being dropped.
There must be something specific about your setup that causes this.
You're using 4.6.2? Try applying all of the patches in sys/netgraph
that are in 4.7-REL that you don't have in 4.6.2... ?
