Bridge between the eth0 and eth1 in server that all traffic will flow in eth0. and that would'nt be establish ip. I will give you that ip to enter server, and in this server will CentOS. This is need to be routing eth1 to internet. I have server, can connected with eth0. But i need to bridge eth1 to eth0 to connect it to internet. eth1 can not would be publish ip. .And also i think need to configurate /etc/sysconfig/network-scripts/route-eth1/. Bellow you can see server details.
