Interestingly enough, I found that my port 113 appeared to be "closed" while all other ports I tested (up to 1056) using the "Shields Up" program seemed invisible.
I added a rule in /etc/shorewall/rules DROP net fw tcp 113 then the port showed up as "stealthed". Ahh, ----Why did I have to do that? --- While looking for the answer to that question I learned a little about port 113. auth or ident if I'm not mistaken is what it's called and it's vestigial. I sort of recall reading about why it is "closed" on some routers. . . . Apparently some servers, like some mail servers, upon receiving a request on the mail port send a "auth" or "ident" request on the auth port and will wait until it's replied to or rejected, or times out before fulfilling the original request.

Terry, Install Nessus, and test away. There are on-line services too, but they usually want money to test you external connection thoroughly.
