A router includes a firewall that protects the LAN from the 
Internet by blocking incoming data traffic on non-standard 
ports. The firewall has external ports available to the Internet 
and also internal ports available to the LAN. The gateway 
operates on port 3000. In order to allow Internet access 
to the Mac web host computer, the firewall internal port 
3000 must be opened to TCP traffic. The firewall external 
port can be set to any unused port number; however, it is 
recommended to select 3000 as the TCP external firewall 
port to keep it consistent. 
The following steps describe how to setup the router from 
a Mac computer:
STEP 1) Click on the Safari icon to launch the web
browser.
STEP 2) Enter the router IP address and press enter.
STEP 3) Enter the router user ID and password at the
login page if required.
STEP 4) Find the router port forwarding rules. This
feature can have other names depending on 
the manufacturer of the router. Other names 
include port address translation, network address 
translation or applications and gaming.
STEP 5) Name the port forwarding rule (such as tN4
Gateway), open external TCP port 3000, and 
then open internal TCP port 3000.
STEP 6) Enter the static LAN IP address of the Mac web
host computer.
STEP 7) Save the settings and log out of the router.
The router configuration is now complete and the web 
browser window can be closed by clicking on the red dot 
in the upper left corner.
