I use a 3Com modem at home, similar I am sure to what you have.  You can probably restrict a range or individual.  Likewise, you probably can tell it to restrict ALL but a certain set of them.  443 is the SSL port, 80 is http, 21 ftp, 22/23 are ssh i think.  1433 is SQL server.   Try seeing if there is a way to restrict everything and then slowly open just the ports you need.  Don't forget any ports for email (not sure which ports),  AIM, ICQ, etc.  Though you probably can lock these down until someone complains.     At 03:24 PM 4/1/2003 -0600, you wrote: Our firewall (or so im told) is a linksys cable/dsl modem. It was set up by an outside contractor while I was still away at university. I can get in there and change the filters. At the moment it does not look to be filtering anything, but it only lets me filter a range of ports not individual ones. Am I safe blocking off UPD 135 through 138 and TCP 135 through 445? A.
