Hi,

I am new to linux. I want to setup a router on linux PC with following config:


GW-------SW-------------[eth0 linux box with redhat 9.0 eth1]--------client pc

Eth0: 192.168.10.40 with 192.165.10.0 network
Router/GW: 192.168.10.1

Eth1: 192.168.20.1 with 192.168.20.0 network

Client PC: 192.168.20.25


I want to route any type of traffic between eth0 and eth1. What do I need to do?

What is the basic config for router setup?

At present I am able to ping from linux box towards both sides but not from client pc to GW.

Here is “route” command output:

192.168.20.0 192.168.20.1 255.255.255.0 UG 0 0 0 eth1
192.168.20.0 * 255.255.255.0 U 0 0 0 eth1
192.168.10.0 192.168.10.40 255.255.255.0 UG 0 0 0 eth0
192.168.10.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eht1
127.0.0.0 * 255.0.0.0 U 0 0 0 l0
default 192.168.10.1 0.0.0.0 UG 0 0 0 eth0

and

I have enabled IP-forwarding using
< echo "1" > /proc/sys/net/ipv4/ip_forward >

And FORWARD_IPV4=yes in sysctl.conf file.

Please let me know where the things going wrong?


Thanks,
Thiru
