Paul, thanks for the comment. what you suggest is what my original
post was asking about.

Now, the externally visible port is not 22. my original post was asking
for advice on tweaking the router to close 22, since I could find no
method for that in the router's UI. not wanting to have to write iptables
rules for the router, I found another method that effectively shuts off
port 22. 22 IS NOT OPEN to the world any more.
