[thelist] Networking: WIFI: Is this MY connection?

[David Hammond]

Frank,

Try installing Nmap [1] and running it against your external IP
address(es).  Nmap will hammer an IP and report back what it learns as well
as highlighting many types of vulnerabilities.  Only use it for your own
personal network however, as this tool can raise some serious "red flags" if
you point it at a machine you don't own.

Using Nmap I discovered that my ISP actually keeps a port open on my router
for "maintenance" purposes.  All attempts to block this port from within my
router's firewall configuration are simply ignored!

Cheers,
Dave
