I have a number of servers, that act like a accelerator with nginx. Those are behind load-balancers.
I give each website a unique combination of IP addresses from a pool (So each website has a different set of four IP addresses).
I need to assign those IP addresses to accelerators, so they accept the packets that comes from the balancers.
And it can be done in linux.
P.S. I'm not trying to start a flame war FreeBSD vs linux, I need to know how to do the same thing, so I can avoid using linux on accelerators.
