Linux 2.2+ supports simple stateless 1:1 NAT with no protocol translation (with an ip rule ... nat rule; see the iproute2 documentation). This is simple and efficient, but most people need protocol translation e.g. to let FTP still work. It also supports 1:n NAT in form of masquerading with protocol translation. HOWTOs exist. Linux 2.4+ supports all the same; plus in addition a new NAT module from netfilter which supports protocol translation and more or less full M:N NAT.
