I am connected to Internet through cablemodem.
My firewall is Zone Alarm Free, version 7.0.483.000
Just out of curiosity I tested my firewal with ShieldsUP, https://www.grc.com/x/ne.dll?bh0bkyd2
It shows that I have ports 111 and 113 open, 22, 25, and 135 stealth, and all others, until 1055, closed.
Now this page test IP address 190.X.XX.XXX, which is not my internal IP, which is 10.XXX.X.XX
Are they testing my firewall or the one of my ISP ?
On the other hand, http://www.auditmypc.com/firewall-test.asp , tested the same address 190.X.XX.XXX, founding ports 111 and 113 open. Moreover http://www.auditmypc.com/anonymous-surfing.asp , found my internal address 10.XXX.X.XX.
I remember that, while I had a dial-up connection, Shields Up showed all my 1055 ports as stealth. I do not remember if I made this test after installing cablemodem.
Should I be concerned ?
Is there a way of testing my internal IP address ?
