Ok, so my system has 2 network cards. Maybe I only use one of them, or maybe they need to be physically connected in a certain way (one to LAN, the other WAN). |

Before asking this question, with the knowledge and understanding that we all already have, don't you have to first have to explain how you're going to ensure that eth0 is always assigned by the system to the first NIC and eth1 always to the second NIC? |
