Re: Tech Tip: This is how You Disable Dcom & close Down Port 135

| Possibly being a security risk if your firewall is not blocking this port.

| Check to see what ports are currently open. This is best done when you first

I use a Linksys BEFSR81 Cable/DSL Router which uses NAT Translation and I specifically block
TCP/UDP ports 135 ~ 139 and 445 on the Router. Most, if not all, Cable/DSL Routers have
simplistic FireWall constructs. Therefore I have no problems and I need no modifications on
my LAN side nodes. :-)
