Dynamic IP in ADSL

Dynamic IP in ADSL

[Alejandro Cabrera Obed]

Hello, I have an ADSL connection to Internet and I want to set an Iptables
firewall. Just one  question:

Do I have to use in my firewall script the IP of my ADSL interface or just
do I have to use the "ppp0" variable and don't care of the IP address
assignment changes ???

Thnks again.

Alejandro

I've been doing a similar thing and you can use ppp0 and it'll work no
problems.  I believe that you should use MASQUERADE if you are likely to
have your external ppp0 IP address change.

Hope that answers the question!

Steve
