Routing

Routing is the act of moving information across an Internet from a source to a destination. Along

the way, at least one intermediate node typically is encountered. Routing is often contrasted with

bridging, which might seem to accomplish precisely the same thing to the casual observer. The

primary difference between these two are bridging occurs at Layer 2 (the link layer) of the OSI

reference model, whereas routing occurs at Layer 3 (the network layer). This distinction provides

routing and bridging with different information to use in the process of moving information from

source to destination, so these two functions accomplish their tasks in different ways. The Routing

screen is shown in the figure below.

Port Forwards

forward

, also called Virtual Server, forwards packets destined to ports in the first range to

the LAN machine with the specified IP address. You may optionally specify a second range. (The

range should not overlap the first range.)

Application Specific Port Forwards

The function is used for special applications whose outbound ports differ from the inbound ports.

For this feature, the SkyZhone Repeater will watch outbound data for specific port numbers.

The SkyZhone Repeater will remember the IP address of the computer that sends a

transmission requesting data, so that when

the requested data returns through the SkyZhone Repeater, the data is pulled back to the proper

computer by

DMZ IP Address

The DMZ feature allows one local user to be exposed to the Internet for use of a special-purpose

service such as Internet gaming or video conferencing. DMZ forwards all the ports at the same
