Configuring Diald on Gateway

[mcbeal]

Hi,

I'm currently using the Diald program. My situation is that I'm connecting my PC to a hub (which is connected to a gateway installed with an adsl modem). When the gateway detect packets for external network, it will run a script to activate my adsl modem. At timeout, it will run another script to down it. I'm using dynamic IP. What if I want to telnet or ftp to my internal network without activating my adsl link? For example, my gateway is pc1 and my clients are pc2 and pc3. If I ftp from pc2 to pc1, diald will dial out to internet. What should I do?

Or can someone teach me how to write a simple daemon to do this?

What I need the daemon to do is to constantly check for packets coming from a certain interface. If the packets are meant for internal network, I will run a script and if it's for external network, I'll run another script. It has to have timeout set for auto bringing down of the external link due to idle.

You might be able to do this w/ the filtering in the diald program.

How do I set the filter?
