I suspect that's a spurious conclusion---you're firewall and some of
the intermediate network infrastructure might simply be configured not
to respond to pings.

VASSAL's game server is on port 5050 on our machine. The port you're
using locally to connect to it could be anything above 1024. I don't
understand why what you're doing would help, since our game server isn't
initiating connections to client machines. (Nor is our web server, which
people had similar trouble connecting to.)

I think it would be a good test to check whether you still have the
problem after setting your router back to the way it had been. If so,
then clearly your changes were effective---but then I think some further
investigation would be in order as to _why_.
