How to Connecting two different network in redhat linux 9

hello friends,

I have linux server with three ethernet cards.

eth0 : 202.66.55.100 --> gw 202.66.55.97
eth1 : 192.168.0.1 --> gw 202.66.55.100
eth2 : 192.168.1.1 --> gw 202.66.55.100
default gateway : 202.66.55.97

eth0 act as gateway to share internet to two networks throu eth1 and
eth2.

how to access from client eth1 network to client eth2 network throu
redhat linux 9 server.

Every hint is appreciated.

with regards

pvn

Set the default gateway for the machine on network eth2 to 192.168.1.1
for eth1 to 192.168.0.1, enable ip forwarding and masquerading and
you're set.

See the firewall-howto about how to setup the firewall.

I think you need the following.

On the eth1 clients:

route add -net 192.168.1.0/24 gw 192.168.0.1 eth0

On the eth2 clients:

route add -net 192.168.0.0/24 gw 192.168.1.1 eth0

Might be interesting to see the output of /sbin/route -n You can not
use 202.66.55.100 as a gateway on either 192.168.0.x or 192.168.1.x
because it's not on the same wire. A gateway is the IP address of the
host ON YOUR WIRE that you send packets to for onward transmission to
some other network (or more commonly, the world).

eth0 is just an interface. The thing that is doing the sharing (forwarding)
is the computer - specifically, the kernel.
