If you have not set up forwarding for port 22 on the router, it is 
already closed.  You do not need to do anything.

If you want to verify this, just try to connect to port 22 from outside 
your network and see what happens.

Actually, connecting to port 22 works fine, or did until my last hacking
session on the router. Which is why I wanted to make it inaccessible.

My current "solution" is to forward 22 on the WAN side of the router
to
9 on the LAN side of the router. since 9 on the LAN side has no services
attached, the incoming connection fails. which is what I wanted.

if you're forwarding WAN port 2222, I do not understand what your router 
is doing with port 22, unless the router itself is also running a sshd
