public ip X point A (linux box) <-> routed wireless net <-> public ip X point B
 
Hello

I have a linux box with an public ip. I have to "forward" this public ip transparent to an other machine over a routed wireless network which I have full access. How can I do that?
public ip X point A (linux box) <-> routed internal net <-> public ip X point B
I'm pretty stucked :-(
Do I have to forward all ports on point A of the public ip X to an internal ip at point B and there again a port forward form this internal adresss to a public address Y which will be the default gateway for public ip B??

How is this called? Is there any expression/term for this problem to search on the net? I have tried several searches but nothing found about this theme...

Thanks a lot for any help!!

If I understand you, NAT does that.

Thanks for answer
I was thinking of that but have my doubt it will work.
I have to connect a cisco 1800 which will open a VPN but this router is in a "private" wireless network and must have a public ip there...
Nobody has used already something like that??
