I wanna make a new target like SNAT..

[JinHyung Park <jinhyung@gmail.com>]

hi..
 i want to make a new target that works like SNAT, but M:N SNAT..
 i mean, there are 50 computers and each has a private ip like 192.168.0.x..
 10 computers need a specific ip of my 50 real ip.
 so, i want that computers to give given range IPs, and another computers 
follow anoter iptables rule.
 for example, i have 1.1.1.1~1.1.1.50 ip, and 1.1.1.1~1.1.1.10 is special 
IPs..
 and my 50 computers has a private network, 192.168.0.1~192.168.0.50,
 some computer that need specific IP assign ( range 1.1.1.1~1.1.1.10 ) and 
another 40 computers just follow other iptables rule..
 (like,
iptables -t nat -A POSTROUTING -d 192.168.0.1-192.168.0.50 -j NEWTARGET --to 
1.1.1.1-1.1.1.10
 and, if all 1.1.1.1-1.1.1.10 are used, other private computer follow 
another rule.. )
 i checked ipt_NETMAP.c, just my thought, make a newtarget likes NETMAP with 
idea like ip pool, but i don know how to pass the next rule if all 
1.1.1.1-1.1.1.10 are used. if there is no IP, just return NF_ACCEPT ? ;; 
 does I make a sense?
 please help me...
