I can reproduce this with my m0n0wall at home (FreeBSD
client/PPPoE/ADSL) too. The problem doesn't seem to be that MSS
clamping is not working, but rather that NetBSD sends packets larger
than [MSS + 40 bytes], which are then fragmented and the fragments
blocked by ipfilter for some reason.

Turning off timestamps in the FreeBSD client (sysctl
net.inet.tcp.rfc1323=0) makes it work.

This is probably related:
