I'm getting my machine to slowly work with it's ppp connection via isdn. It dials, connects and I can get out to the internet and browse on the gateway machine only. I'm running the 2.4.5 kernel, with iptables. However what I'm running into is when I try to follow the basic rules from either the HOW-TO or from last month's Linux Journal, I keep getting errors telling me that iptables isn't compiled into my kernel or that it needs to be upgraded. Something about not finding the filters table if I recall... What happened was when I reloaded my machine, I picked both the ipchains and iptables packages. Somehow I think that neither got compiled into the kernel. I can modprobe it, and then when doing an lsmod|grep ip_tables it shows up. for the time being, I also put the modprobe ip_tables in my rc.local file to get it to work. I still get the error message that it can't find the filters table. Any ideas on what more I can do to get this to work? Also, I'm trying to write/get a script that will keep a persistent connection up on my ppp. I've read the PPP how-to, but the samples they give are if you are not running pap/chap. What would be the best way to go about scripting what I need? I'm assuming that I will need to place it into cron, have it ping every 5 minutes or so, but beyond that I don't know. I'm really quite horrid at scripting, if anyone can help me out I'd appreciate it. Thanks, Shawn
