Securing ports


S

Steven

I have a router and the firewall is basically using the default settings.
The problem is that when I do a security scan at http://scan.sygate.com/ it
says: "This port has responded to our probes. This means that you are not
running any application on this port, but it is still possible for someone
to crash your computer through known TCP/IP stack vulnerabilities." for two
ports. I am using a dlink router and would like to know how to secure the
ports without hindering my ability to browse.

Thanks In Advance

Perhaps you could stretch this rule to at least telling us which ports you
are concerned about?

Sygate has a free firewall for download it won't interfer with the one in
the router.

So, why are you asking here and NOT in a FireWall News Group ?

In any case, just block the ports in the Router. As always, I suggest blocking TCP and UDP
ports 135~139 and 445.
