I checked my IPaddress from cmd prompt (IPconfig/all).

It showed an IPaddress (IPv4 address): ........(preferred)
it then showed the DHCP and DNS addresses.

I went to GRC. The IP address did not match. I cross-checked the IP address of my pc with online check. It matched with the IP address shown by the GRC. Why does the address does not match?

GRC showed my port 22 is open (remote protocol). How do I use zonealarm to close it?

My OS is win7 64 bit ultimate. I use Zonealarm Extreme security and DrayTekVigor 2820 series...
