no problems from pilosoft network, you can probably save a lot of
bandwidth on that picture, but for testing there shouldn't be a problem
that I know of.

have you tried serving from a another lightweight server like boa
(me not sure if it builds on BSD)
don't know what you can do about M$ clients, but use mtr vs traceroute
whenever possible it's ported to bsd. http://www.bitwizard.nl/mtr/
some hops will just drop direct icmp packets, but route them and
everything else fine, traceroute cannot get over that. mtr will show you
the rest of the route.
(disregard these Sent numbers that's a local config)
