One can NAT to a range of IP addresses. That used to produce a rough
round robin distribution of addresses; I'm not sure if that is still the
case. Thus you would have:
iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source
1.1.1.1-1.1.1.254
or something similar.
Although it is not complete, the ISCS network security management
project (http://iscs.sourceforge.net) automates the creation of even the
most complex NAT including many to some, some to many, overlapping and
nested NAT. Good luck - John
