If your provider doesn't have things configured correctly, it is possible
for
reserved IP numbers to be leaking onto your line. Some providers are
notorious
for doing that. I don't know how likely that is with DSL.
If your FreeBSD gateway system is doing NAT (and is correctly configured),
then
this explanation doesn't work anyway, because the address(es) you expose
to the
outside world is (are) not the 192.168 address. Perhaps it could be a
sign that
your NAT is misconfigured.
