how can i do this in linux
i have mandrake 9.2
please send for me a example to undrestand better

sorry for my english :p

Just to clarify, you have 127 world routable IP address and want to map on a 1 to 1 basis these real IPs to fake 192.168.x.x class C addresses? Wow, first I'm wondering why, just NAT all of the 192.168.x.x subnet through a single world routable IP address or dhcp lease the 127 world routable IPs to each of the clients and do away with the the unnecessary routing. Windows does mangle things a bit with "Internet Connection Sharing" and such, under Linux you can get very very precise with NATing a connection and research your way around the bugs that crop up later very easily.

Don't worry about the english, just try to be as verbose as possible when explaining things. I find it easier if you do not worry about repeating things over and over again, stylisticly bad, but we're not writing great works of literature here, so its not a concern.

Also, this is in the "wireless networking" subforum, you need to be in just normal networking. I'll get the post moved.

Btw, if I doesn't like DHCP how can I achieve this goal using iptables?

You're going to have to start over, what have you got and what exactly are you trying to do?
