I have big ideas for the gaming situation, are you sure the servers are up
for other people?  Also,  what did the traceroute look like from your
machine to the servers, and from a nonrelated machine to the servers?  If
you give us an ip, we can try too.

I can see linux not showing 10.x hosts in traceroute... If incoming data
is from an ip in a range that is supposed to be a private subnet, then
perhaps a firewall on linux or something else would purposely ignore
private range IP's coming from an external interface.  If its ignoring the
messages traceroute causes machines to report back with, traceroute will
show a * for no reply.
