[RH8] Internet works, but ppp0 is inactive

[rubenski]

Hi. I am totally new to Linux and to this forum. I have just installed RedHat 8 and configured my internet connection on eth0 through RH's graphical interface.
I get ip and dns's from my ISP with DHCP. I also added a xDSL connection on eth0. I understand this is called ppp0, because ppp0 now shows up in network settings. ppp0 however, is inactive, but internet works fine! Whenever i try to activate ppp0, it will activate after a long time and then it immediately deactivates again.

I had a similar thing happen. Check KPPP to see if it is responcible.
Plus - If it works, what's to fix?

Well, i was planning on using IPtables to route the connection to my network. I am not sure if these rules will work when ppp0 is inactive. How do i check KPPP? Can i do it using the GUI or should i use the command line?

IPtables should work fine for your purposes. It references your NIC's as eth0 and eth1. It does however reference dial-up modems as ppp0 in some circumstances. It should work fine for you. KPPP is located somewhere in that mess of a start menu (I am at work so can't tell you exactly where it is).

Ok, thanks for taking away that uncertainty. Do you know a good step-by-step, totally idiot proof tutorial to get my network up with iptables? I have seen many NAT howto's,iptables tutorial's, etc, but i didn't get it to work so far.

I personally recommend Guarddog. It's a GUI frontend for IPTables. Really easy to use and all thats left in the port forwarding. It's at

Oh yeah, and welcome to Linux the water is fine.:)

I second that on Guarddog. Recommend compiling the source if your distro's rpm isn't available.

Simonzone put up a rpm for RH8 not too long ago. I have tried it out and it works great. You should be all set. Good luck. Iptables takes a little patience but it rules...
:D
