While on the subject of modems, here is a question for ya. I am running Fedora Core 2 on a system with a Hayes external serial modem. I would like to make this system dial-out to my ISP and use it as my firewall between the ISP and my private network.
I tried this before, but I forgot what problems I was having. I would like to be able to do this all from command line so that I can place everything in a script so that when the connection drops it automatically redials to the ISP. Any suggestions?
For dialling automatically I would use ppp on demand. All you have to do is pass the demand and persistent options to pppd. If you also set the onboot parameter, you will not have to do anything. Just boot the computer, and if a program requires internet access, pppd will take care of dialling and connecting.
I also run an ip-up.local which I've symlinked to a firewall script so when the ppp connection is established, it runs the firewall script (which in turn sets up the firewall according to the external ip address the connection now holds).
Run's beautiful - no maintenance required.
