Network Address Translation daemon, commonly known as natd is a daemon that accepts
incoming raw IP packets, changes the source to the local machine and re-injects these
packets back into the outgoing IP packet stream
Clients on the LAN can make outgoing connections to the world but cannot receive incoming ones. This presents a problem if trying to run Internet services on one of the LAN client machines. A simple way around this is to redirect selected Internet ports on the natd machine to a LAN client
