Question RedHat Linux 9 as a internal Router

Dear All,

I have a problem from last four days, is there any one to help me to solve this problem.

I have to different network address scheme


I want to use redhat 9 to act as a router for these two network.
Following are steps which I have done.

1. installed 2 NICs
2. one ip is netmask
3. seconds ip is netmask
4. enabled ip forwarding. echo "1" > /proc/sys/net/ipv4/ip_forward.

client machines form both networks can ping both ips of this router but

it can not access any other computer on other network.

I need all traffic should route with its real ip. I mean dont want to configure nat (masquarding).
