well, not 2222, but another port I won't identify here, and it
is forwarded to 22 on my linux box. The idea was to put ssh on an
unusual port. but I couldn't figure out how to close port 22, which
was open by default on the router, apparently. I still don't see any
way in its UI to do it, and didn't especially want to have to write
a custom firewall rule. So I just forwarded WAN/22 to port 9 on
the LAN side of the router.
