Yes, the installation from ISO, but the network cards for my case, eth1 eth2 are the ISP modems with public addresses.
when installing the eth0 LAN GREEN card, the ip is assigned by yourself. after completing the installation and enter from the web https://xxx.xxx.xxx.xxx:980
the network interfaces have no outlet to the internet, and would have to do the above steps to work by dhcp. @giacomo regards
