I installed two ethernet cards in my server named
external eth0, Internal eth1. eth0 has a gateway
10.9.93.225, Lan card IP address is 10.9.93.226
eth1 card IP address is 131.107.1.1.

I can ping from pc which has IP address 131.107.1.2
to address 10.9.93.226 and 131.107.1.1

Also I can ping from 131.107.1.1 to 10.9.93.226 AND
10.9.93.225.

But unable to ping from 131.107.1.2 to 10.9.93.225.


10.9.93.226 is connected to satellite modem IP Address 10.9.93.225.

I can not access internet from 131.107.1.2 but can
access from 10.9.93.226

I tried by changing cards also but the problem still exists.

Help Plz to solve this !!!!

Although very much off-topic, check the following:
1) what software is on your pc

2) does your PC "know" that it needs to forward the packets recieved on 131.107.1.1 towards 10.9.93.225 ?

If your PC has no software capable of forwarding packets, then your PC will not do anything with packets that are sent to it but not "addressed" to it.


If your PC has forwarding software (or is configured as such) then you also must make sure that PC nr 2 (with ip 131.107.1.2) has a default gateway towards 131.107.1.1

Furthermore you will have to use address translation somewhere as your 10.x.x.x address belongs to private adress space and cannot be routed on the internet.

Your addresse 131.107.1.x musrt also be translated as these belong to microsoft..
