Question

:

What’s the difference between “Internal Port” and “External Port”?

Answer

:

Internal Port means which port the local server is listening to. External Port means

which port the router is listening to. For example, local station John’s running Telnet Daemon

on port 64623, then internal port is 64623, external port is 23. Suppose Internet user

initializes a Telnet connection request to this router’s public IP address, router will recognize

that this is a Telnet Connection request to a station. According to existing forwarding rule,

router will first translate the packet’s destination port to be 64623, and then forward this

request to host John. If we designed “External port” only, then we’ll have trouble to setup two

FTP servers locally simultaneously, since there will be 2 FTP daemons running, and that’s

hard for router to figure out which connection request should be redirected to which FTP

daemon.

4.2.11 Advanced - Port Triggering

This page allows configuration of dynamic triggers to specific devices on the LAN. This allows

for special applications that require specific port numbers with bi-directional traffic to function

properly. Applications such as video conferencing, voice, gaming, and some messaging

program features may require these special settings.

Some services use a dedicated range of ports on the client side and a dedicated range of

ports on the server side. With regular port forwarding you set a forwarding port in NAT to

forward a service to the IP address of LAN side host. The problem is that port forwarding

only forwards a service to a single LAN IP address. In order to use the same service on a

different LAN computer, you have to manually replace the LAN computer's IP address in the

forwarding port with another LAN computer's IP address.

Here we define 2 kinds of ports, “Trigger Port” and “Target Port”. Trigger port is defined as

the service request with a specific destination port number sent from a LAN side host. Target

Port is defined as the ports this specific application requires clients host to listen. So, server

will return response to these ports.

Let’s give an application scenario to get a clear concept.

Suppose,

1)

John requests a file from the Real Audio server (port 7070).

2)

Port 7070 is a “trigger” port and causes the wireless router to record John’s computer IP

address. Ubee wireless router associates John's computer IP address with the "target"

port range of 6970-7170.

3)

The Real Audio server responds to a port number ranging between 6970-7170.

4)

Ubee router forwards the traffic to John’s computer IP address.

5)

Only John can connect to the Real Audio server until the connection is closed or times

out.

Description

Trigger Range

The trigger port is a port (or a range of ports) that causes (or

triggers) the router to record the IP address of the LAN computer

that sent the traffic to a server on the WAN.

Start Port

Type a port number or the starting port number in a range of port

numbers.

End Port

Type a port number or the ending port number in a range of port

numbers.

Target Range

Target Range is a port (or a range of ports) that a server on the

WAN uses when it response to service requests. The router

forwards the traffic with this port (or range of ports) to the client

computer on the LAN that requested the service

Start Port

Type a port number or the starting port number in a range of port
