this is my network design.
i have two interfaces in my ubuntu 14.04 LTS desktop. one is eth0 and other is eth1. I have two routers for that.
DSL wire is coming to router1 than wire from router1 coming to eth0 interface. So i'd be able to connect to internet but i m not, until i run the "dhclient" command. then eth0 is setup to send traffic to eth1 and a wire from eth1 is connected to router2. Now i am connecting my phone with wifi to that router2 it connects but i am unable to access the internet.
my IP forwarding is OK ! n I want to access internet plus the routing between two NICs, so that i can access internet from router2 also !!!
And it was working properly a week ago.
Please help to properly configure it.
