Add/Edit Virtual Server

In this section you can add an entry to the Virtual Servers List below or edit an

existing entry.

Enable

Entries in the list can be either active (enabled) or inactive (disabled).

Save

Saves the new or edited virtual server entry in the following list. When finished

updating the virtual server entries, you must still click the

Save Settings

button

at the top of the page to make the changes effective and permanent.

Virtual Servers List

The section shows the currently defined virtual servers. A Virtual Server can be

changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you

click the Edit icon, the item is highlighted, and the "Edit Virtual Server" section is

activated for editing.

You might have trouble accessing a virtual server using its public identity

(WAN-side IP-address of the gateway or its dynamic DNS name) from a

machine on the LAN. Your requests may not be looped back or you may be

redirected to the "Forbidden" page.

This will happen if you have an Access Control Rule configured for this LAN machine.

The requests from the LAN machine will not be looped back if Internet access is blocked at

the time of access. To work around this problem, access the LAN machine using its

LAN-side identity.

Requests may be redirected to the "Forbidden" page if web access for the LAN machine is

restricted by an Access Control Rule. Add the WAN-side identity (WAN-side IP-address of

the router or its dynamic DNS name) on the

Advanced

→

Web Filter

screen to work around

this problem.

Advanced_Special Applications

An application rule is used to open single or multiple ports on your router when the router

senses data sent to the Internet on a "trigger" port or port range. An application rule applies

to all computers on your internal network.

Parameters for an Application Rule

Example:

You need to configure your router to allow a software application running on any

computer on your network to connect to a web-based server or another user on

the Internet.

Name

Enter a name for the Special Application Rule, for example

Game App

, which

will help you identify the rule in the future. Alternatively, you can select from the

Application

list of common applications.

Application

Instead of entering a name for the Special Application rule, you can select from

this list of common applications, and the remaining configuration values will be

filled in accordingly.

Trigger Port Range

Enter the outgoing port range used by your application (for example

6500-6700

).

Trigger Protocol

Select the outbound protocol used by your application (for example

Both

).

Input Port Range

Enter the port range that you want to open up to Internet traffic (for example

6000-6200

).

Input Protocol

Select the protocol used by the Internet traffic coming back into the router

through the opened port range (for example

Both

).

Schedule

Select a schedule for when this rule is in effect. If you do not see the schedule

you need in the list of schedules, go to the

Tools

→

Schedules

screen and

create a new schedule.

With the above example application rule enabled, the router will open up a range of

ports from 6000-6200 for incoming traffic from the Internet, whenever any computer

on the internal network opens up an application that sends data to the Internet using

a port in the range of 6500-6700.

Add/Edit Special Applications Rule

This section is where you define and edit Special Applications Rules.

Save

Saves the new or edited Special Applications Rule in the following list. When

finished updating the special applications rules, you must still click the

Save

Settings

button at the top of the page to make the changes effective and

permanent.

Special Applications Rules List

The section shows the currently defined special applications rules. A special

applications rule can be changed by clicking the Edit icon, or deleted by clicking the

Advanced_Gaming

Multiple connections are required by some applications, such as internet games, video

conferencing, Internet telephony, and others. These applications have difficulties working

through NAT (Network Address Translation). This section is used to open multiple ports or a

range of ports in your router and redirect data through those ports to a single PC on your

network. You can enter ports in various formats:

Range (50-100)

Individual (80, 68, 888)

Mixed (1020-5000, 689)

Example:

Suppose you are hosting an online game server that is running on a PC with a

private IP Address of 192.168.2.50. This game requires that you open multiple ports

(6159-6180, 99) on the router so Internet users can connect.

Port Forwarding Fields

Name

Give the rule a name that is meaningful to you, for example

Game Server

. You can

also select from a list of popular games, and many of the remaining configuration

values will be filled in accordingly. However, you should check whether the port

values have changed since this list was created, and you must fill in the IP address

field.

IP Address

Enter the local network IP address of the system hosting the server, for example

192.168.2.50

.

TCP Ports To Open

Enter the TCP ports to open (for example

6159-6180, 99

).

UDP Ports To Open

Enter the UDP ports to open (for example

6159-6180, 99

).

Inbound Filter

Select a filter that controls access as needed for this rule. If you do not see the filter

you need in the list of filters, go to the

Advanced

→

Inbound Filter

screen and create

a new filter.

Schedule

Select a schedule for the times when this rule is in effect. If you do not see the

schedule you need in the list of schedules, go to the

Tools

→

Schedules

screen and

create a new schedule.

With the above example values filled in and this Gaming Rule enabled, all TCP and

UDP traffic on ports 6159 through 6180 and port 99 is passed through the router and

redirected to the Internal Private IP Address of your Game Server at 192.168.2.50.

Edit/Add Game Rule

Here you can add entries to the Game Rules List below, or edit existing entries.
