How to configure a network?

[Sachin Rane]

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'.

UG       0      0        0                 eth0

 

 

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.

 

[root at Client #1 Ananth]# /sbin/routeKernel IP routing table

Destination        Gateway           Genmask         Flags    Metric
Ref    Use          Iface

0        0             eth0

192.168.10.0     172.24.4.16       255.255.255.0   UG       0          0
0             eth0

169.254.0.0       *                       255.255.0.0       U          0
0        0             eth0

default               172.24.4.1         0.0.0.0              UG       0
0        0             eth0

 

------------------------------------------------------------------------

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
