On both machines ensure, that IP_Forwarding is enabled. If not type :<br />

To make it started on boot-time, add the above line to /etc/rc.d/rc.local file.<br />

Check that the routing is correct. <br />

Hi,<br />
<br />
I've just bumped into a problem, which is that I have two PCs of linux<br />
installed on them and both have 2 ethernet cards.<br />
They are meant to work as physical bridges between two local nets.<br />
One is set up as 10.120.0.9 for eth0 and 10.200.22.9 for eth1 while<br />
the other has 10.200.20.9. for eth0 and 10.200.21.9 for eth1.<br />
<br />
They are connected on their eth1 interfaces with a cross-link cable.<br />
<br />
I would like make a double gateway of them so that all traffic could<br />
pass on from the 10.200.0.0/16 network to 10.120.0.0/16 network and vice<br />
versa.<br />
<br />
Could anyone help me in the question how to configure these two machines<br />
as gateways and IP forwarders?<br />
<br />
Thanks in advance!<br />

IP bridges made of linux machines

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
