Hello. I've got a firewall which has public IP xxx.xxx.xxx.2 on its first NIC. This is bridged with a second NIC which holds xxx.xxx.xxx.0/24. (I also have a third and fourth NIC which runs two private IP networks, which are NATted, but I don't think this matters). Everything is ok, but now I'm in need to also have a second public IP network on the second NIC, let's say yyy.yyy.yyy.0/24. A single upstream router provides us both public nets, but obviously with two different gateways (xxx.xxx.xxx.1 and yyy.yyy.yyy.1). The question is: is this possible? Do I only need to attach the additional yyy.yyy.yyy.0/24 boxes to the same switch? Do I need to ifconfig alias yyy.yyy.yyy.2 on the first NIC? What about the gateway then? Do I still set the first one only? My answers would be: Yes, No, Yes. I thought I'd ask, however. bye & Thanks av.
