I am still a little new to it and would like some pointers to getting a Also I am obtaining my provider interface IP dynamically with dhcp and the ip masquerade script I have only has a single definition at the top. Any clues how to get the script to figure my IP at boot time and also update the masquerade rules when if my dynamic IP is reassigned? I want to configure secure dynamic DNS for the machine as well to update my name servers when my IP changes. I am not interested in packages like guarddog or things that remove me from scripts that I can just plop in on my own. any advice on locating good web pages or howtos that can help me here. Looking forward to responses. Thanks in advance, Noah </body> </html>
