I'm using netbsd 1.6 PPPoE.  I see these problems on the local machine.

PPPoE seems to set the interface MTU appropriately:

pppoe0: flags=8851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST> mtu 1464
        inet 66.96.18.31 -> 69.90.48.1 netmask 0xff000000
        inet6 fe80::280:c8ff:fef8:f2d3%pppoe0 -> :: prefixlen 64 scopeid 0xa

I do use ipnat for my home network, and I have it configured with
mss-clamping.  It worked fine until yesterday.
