Re: [PCTECH] Need firewall protection,

Well, I would discount the "dynamic"ness of the IP address.  I know they are
set up dynamic, but typically the way DHCP works is that if the computer
keeps requesting the same address during the lease time, it will keep
handing out the same address.  I have had the same ip address form my cable
modem for the last 2 years.  Thankfully, so as I don't have to keep changing
my DNS for home server. ;)

Other than that, you are completely correct.  They can only get in through
opening ports in the router configuration or from what you request to be
pulled in (webpages, email, installed programs, etc).
