My ISP allow me to have 5 dynamic ip addresses. Yet, it's locked to the MAC address (i
think) .. currently my network look like this:
[ Internet ]----[ 16-ports Unex Switch ]----[ my network ]
..and in the local network, I have 3 servers and my two workstations. My idea was to put
one server "infront" of all other computers, like:
[ Internet ]----[ FreeBSD ]----[ 16-ports Unex Switch ]----[ my networks ]
..and have the FreeBSD server holding all 5 ips from my ISP and then NAT/Forward it to
the rest of the network.. like a transparent firewall/logging server. Like having 3 of
the ips going to my 3 servers.. and have another IP for NAT:ing the two workstaions
which uses a local IP range.. or something.
My porblem is to get the FreeBSD server request 5 ips on the same NIC using the DHCP
protocol. Is it even possible?
