router setting

baremacho · 10-24-2004, 10:05 AM

hi guys,

I just set up fedora core 1 as my router.
The problem is that I can't access internet(I mean that I can't browse website)
from my linux box.But my LAN computers can access internet and browse
website.Maybe I misconfigured the iptables things or misconfigured how to assign ip to each ip cause I assign them with GUI and not by the command.

I got my eth0 as my external NIC and eth1 as my internal NIC.

okay,this is part of my firewall scripts:

INNER_NET=192.168.0.0/24
FWALL_IP=192.168.0.1
INNER_PORT=eth1
OUTER_PORT=ppp0
IPTABLES="/sbin/iptables"
MODPROBE="/sbin/modprobe"

and so on...

and i use rp-pppoe to connect to internet which means i have dynamic ip.

Can anyone help me how to solve this problem?

thanks..

Do you have your ISPs DNS servers listed in /etc/resolv.conf?

The setting of 127.0.0.1 points to your local machine. This is if you have an own DNS server running on the same machine.

don't know where i did the mistake.Maybe I misconfigured the eth0 and eth1 things.
Does anyone know where i should fix it?

First you will have to create a valid setup of zone files for the domains you control.
To understand this you will have to catch up on some reading on how the DNS system is built and how these zone files work. There are graphical programs to do this configuration, but you would still have to know how it works.

If you don't want to serve your own domain you can set up a caching only server.
