At default setting, the network behind Galaxy router is isolated from outside
network to provide safety for the hosts. For SOHO application, you may need to
setup your own WEB/FTP or other kinds of service; NAT (Network Address
Translation) /NAPT (Network Address Port Translation) technology can meet
your requirements.
With this setting, the outer source ports can be mapped to a specified a host at
the LAN side. When the mapping scheme is defined, all the data traffic from/to
those mapped ports will be transferred to the specified host only.
The TCP, UDP or both protocols can be mapped to the destination ports. If the
destination port is not defined, it will be the same port as the source.
Additionally, there is a DMZ (DeMilitarized Zone) host that can be defined.
NAT/NAPT ports mapping is in higher priority than DMZ is. In other words, if a
port has been mapped to a host at the LAN, the data at this port will be
transferred to this host, and not be transferred to the defined DMZ host.
Galaxy router can map up to 16 ports (hosts).
Example.
 WEB Server: maps port 80 to a LAN host address 192.168.8.8
