Hello Guys,
I have a prob with diald, I had posted a message earlier, I think it was a bit too elaborate question for someone to answer. Actually the problem is that any one on the network is able to bring up the link, which I dint want to happen. What I wanted was that only certain users be able to bring up the link, and others can browse only if the link is up by the prioritised user, but as of now a request from any browser on any machine brings it up. I used the "bringup" rule to filter the packet, but dint work. I tried to dig a bit deep into it and came to the conclusion(which may be rong after all) that all the packets gets maquaraded wen it reaches my gateway. I need to get the packets b4 it is being masq'ed to know thw actual IP. How do I do it ?IP chains? If yes please try to be a bit eloborate cos i havent got an experince working on the IP chains. If wat I concluded is rong pls lemme know where I am rong ,and if u have any thing to tell which cud get over this prob.
10x in Advance

Could you post the results of ipchains -L command?

I have never messed with a dial-up account but I do know that iptables is being used a lot now adn documentation is pretty widely available.
With iptables you could specify what int IPs could create a connection.

Hi thanks for the reply ...hewre is the IP chains -L output

Well, maybe in your situation it would be easier to switch to iptables. With ipchains I don't know a method to do this without additional software.
