Hi,
I have a machine (say "MyBridge #1") with 2 network card.
The first network card is connected to "172.24.4.0" network with IP
address '172.24.4.16' and another one is connected to "192.168.10.0"
with IP address '192.168.10.1'.
I wanted this machine to be acted as a router/ bridge/ gateway (I am not
very clear about the exact term).
I wanted any machine present on "172.24.4.0" network can reach machine
present on network "192.168.10.0".
------------------------------------------------------------------------
----------
So here the list of 'route' present on the machine 'MyBridge'.
[root@'MyBridge' kiran]# route

I have set the flag "net.ipv4.ip_forward = 1" in file "/etc/sysctl.conf
"of machine 'MyBridge'.

Here is the 'route' present on machine (say 'Client #1') with IP
address.

I can ping from 'Client #1' to machine "MyBridge #1" on both IP
('172.24.4.16' and '192.168.10.1').
But I cannot ping other machines present on network "192.168.10.0" from
Client#1 e.g 192.168.10.2.
Thanks and Regards,
Sachin Rae
