I have a server with two lan card. On eth0 i have static ip from my isp for internet acces, on eth1 i have an ip from my class (my isp routing my class trough ip from eth0), mask, and the gateway is ip from eth0. I connect a pc on eth1 and i assign another ip from class, with gateway (eth1 ip) and dns (dns from provider). On server ping to google work but on the pc not work. How to root the trafic from eth0 to eth1 witchout nat (i want the computer ip to be visible outdoors) ?.
