That's exactly the symptom I was having due to the window scaling bug in
IPFilter, which I fixed a while back.  Apparently there was a problem
merging the fix into the new kernel.

Try setting the client's receive socket buffer to no more than 65535 and
see if that fixes it.

Although the announcement didn't specifically mention it, the fix for the
IPFilter bug where NAT was screwing up checksums of ICMP errors may have
been lost as well.  The most obvious symptom is traceroute not working,
but it could break PMTU discovery as well.

I don't know why 802.11a/g support was so important that it justified
rushing into 5.3 with known broken basic firewall functionality.
