I am a fairly new Lunux user.

I am trying to setup a test netork as follows:

172.16.4.0 ---> | eth0_inside (172.16.4.2)-- Redhat 9 Box -- eth1_toRouter (172.16.3.10)| ---> router (172.16.3.4)

eth0_inside IP is 172.16.4.2. The default gateway has the eth1_toRouter's IP 172.16.3.10.

eth1_toRouter IP is 172.16.3.10 and its default gateway is the
router's IP 172.16.3.4.

I edited the sysctl.conf file in /etc to put a value of '1' to
net.ipv4.ip_forward. I rebooted the machine.

Result:

I can ping both interfaces, the router, and the inside hosts
from the linux box.

The hosts can ping only up to eth1_toRouter (172.16.3.10). Not
beyond that.

Your help would be greatly appreciated.
