Greeting.

Now for the question...
First the details...

I have two local networks...with 192.*.*.* and 172.16.*.*

They Are two different Floors..

Now for the Question..
I want use two different Internet connections.. nd linux boxes as gateways.
------------Editing it -----------I did earlier also
The Step 1 is using one connection...
The step 2 would come later on.. if conn 1 fails .. then.. I will switch it to a slower conn2 as a backup conn...
-------------Finish Edit..

with eth0 as real IP and eth1 as local IP.
on both boxes..

But now we want to migrate everything to a single box With ONE real IP.

and two diffrent Networks.

that is the
eth0 --> 202.x.x.x (Will be a real IP)
Netmask --> 255.0.0.0

eth1 --> 192.168.0.1 ( Will be the gateway for network one)
netmask 255.255.255.0

eth2 --> 172.16.0.1 (GW for network two)
netmask 255.255.255.0


Any Suggestions on how to do it..

Of somebody has already hacked together a script .. to do route together the network...

Using one router for multiple networks is not complicated in the slightest. However, I'm a bit comfused with regards to the Internet connection, as you first say you want to use two Internet connections, but in the example only one NIC has a public IP address. Could you clarify?

Otherwise, your setup will work if you simply:

• assign IP addresses to each interface
• enable routing on the Linux box
• configure clients on both network to use the relevant IP address on the Linux box as a gateway
• and finally NAT overload all outgoing traffic behind a public IP address
