ip-aliasing

Please detail me the methods.

My thoughts:

put the servers in separate (sub)networks
- the servers are forced to go through the firewall but no NAT is required
assign more IP addresses to the internal interface of the server
- choosing gateway addresses from the clients and servers IP address ranges
split DNS

Netfilter/{iptables, ipset} could be heavily involved, I'm talking about Linux servers. See for example: Destination NAT Onto the Same Network from internal clients

Please do not explain what is NAT or DNS. This is a theoretical question, but my poor English knowledge prevent me to describe it in a fancy fashion.
