NAT & port mapping
Ussualy i work with real address space, but now need to do NAT.
I't s not a problem (linux box) but i need todo mappings.
So, if any person from real world trying to access port 2345 (for exmaple) on router, in real it contact internal machine (192.16.1.1) on some port.
Cheap hardware routers also do this, called DMZ/port mapping.
Please point me to a needed command on linux box.
