The boxes were running FreeBSD-6.1, but I can't really vouch for the particular kernel configuration. It could well be that the problem is with the loose nut behind the wheel, rather than with FreeBSD. :-)
I believe PMTU measurements may only be relied upon for active TCP connections, but it's been a while since I read this code.
It would be useful if non-TCP drivers such as gre(4) could be extended to perform PMTU discovery and auto-tune their MTU based on this, as manually setting the MTU is a bit random and can result in horrible fragmentation when going across the big-I Internet.
I imagine doing this would require changes to the icmp input path and a bit of abstraction.
