For that problem at least, and another that's just emerged in ipfw@ -
also using ipfw kernel nat - all interfaces shown have TSO enabled.
% man ipfw | tail | head -4
Due to the architecture of libalias(3), ipfw nat is not compatible with
the TCP segmentation offloading (TSO). Thus, to reliably nat your net-
work traffic, please disable TSO on your NICs using ifconfig(8).
I couldn't find an ifconfig shown in this thread, so I'm left wondering
whether TSO is configured on the OP's or any of the problem boxes here?
cheers, Ian
