Hi Netfilter list, I would like to know if anyway here have experience trying to make a box act as a DAT system. DAT means that a box can SNAT any IP address behind it. This is usefull on systems that sits in front of a network that may have clients using any static IP address and its traffic should be NATed... Ex: the linux box have an internal IP: 192.168.0.1/255.255.255.0 and a client behind it have a 200.200.200.200/255.255.255.0 IP that should be NATed to access the Internet... Does anyway have tried this before? Is it possible under Linux? Any information will be appreciated. tks in advance... Andre Correa andre.correa@xxxxxxxxx
