Dear Krymson and George,

Thank you both for your answer and help.

I have a doubt regarding the spuffing issue:

Krymson says:

3) The IP 192.168.0.x is not an Internet routable address. Your cable modem, 
or wireless
AP, or whatever you use to get to the Internet will not let that pass through 
to the WAN
side. So nothing to worry about there!

and George says:
Blocking incoming packets to your WAN from any private scheme
of IP addresses -  10.0.0.0 – 10.255.255.255  172.16.0.0 – 172.31.255.255
and 192.168.0.0 – 192.168.255.255 - is a good idea. In networking terms
is called IP Spoofing meaning that someone using any IP from the above range
may deceive your firewall settings and interpreted as someone from your 
internal
network!!

Is there a singularity with these address ranges ?

Best Regards,
