|As far as I know, by default all ports are closed on a SOHO Router and if you want one (or more) open, you have to actually open it (them) manually.|
Just FYI........having any ports open by default on a router kind of defeats the purpose of the builtin firewall inside the SOHO Router.
If you have a new router and you'd like to test, google "shields up" and go to their website and have it run a port scan on you.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
