I got the following ip block from my ISP.

202.51.177.0/29 (Here 202.51.177.1 is my gateway which is located in my ISP's Router, My useable ip is 202.51.177.2 - 202.51.177.6)

I have a linux pc with 2 NIC. I have putted 202.51.177.2/255.255.255.252 in my eth0 which is connected to my ISP And 202.51.177.5/255.255.255.252 in my eth1. My PC is directly connected to eth1. My pc ip is 202.51.177.6/255.255.255.252 and gateway is 202.51.177.5

I can't go to internet. What I have to do in linux box. ip_forward=1 is already enabled. Plz help

It is possible that your ISP router does not have a route to 202.51.177.5/255.255.255.252 that is why the traffic is not coming back.

I (Tukang Nggame) have idea. Your linux pc use network 202.51.177.0/29.
