The NAT (Network Address Translation) feature makes devices on the LAN use the
same public IP address to communicate with devices on the internet, which protects
the local network by hiding IP addresses of the devices. However, it also brings about
the problem that an external host cannot initiatively communicate with a specified
device on the local network.
With the forwarding feature the Mobile Wi-Fi can penetrate the isolation of NAT and
allows devices on the internet to initiatively communicate with devices on the local
network, thus realizing some special functions.
The Mobile Wi-Fi supports four forwarding rules. If two or more rules are set, the priority
of implementation from high to low is Virtual Servers, Port Triggering, UPNP and DMZ.
It contains the following sections:
Translate Address and Port by ALG
Share Local Resources on the Internet by Virtual Servers
Open Ports Dynamically by Port Triggering
Make Applications Free from Port Restriction by DMZ
Make Xbox Online Games Run Smoothly by UPnP
