To add a new application profile:

1.

Open a Web browser and enter

to access the 2Wire i3812V user interface.

2.

Click

on the

Home

page; the

Firewall Status

page opens.

3.

Select

Applications, Pinholes and DMZ

; a page opens showing the computers that are connected to

your i38HG/i3812V and the application list.

4.

Scroll down and click

Add a new user-defined application

; the

Firewall Application Profile Definition

page

opens.

Configuring Firewall

43

5.

Enter the application profile name in the

Application Profile Name

field.

6.

Create a definition for your application that is to be allowed through the firewall.

−

In the

Protocol

field, select the

TCP

or

UDP

radio button. If the application you are adding requires

both, you need to create a separate definition for each.

−

In the

Port (or Range)

field, enter the port or port range the application uses. For example, some

applications requires only one port to be opened (such as TCP port 500); others require that all

TCP ports from 600 to 1000 be opened.

−

In the

Protocol Timeout (seconds)

field, optionally enter a value for the amount of time that can pass

before the application “times out.” When leaving the field blank, the system uses the default

values (86400 seconds for the TCP protocol; 600 seconds for the UDP protocol).

−

In the

Map to Host Port

field, enter a value that maps the port range you established in the Port field

to the local computer. For example, if you set the value to 4000 and the port range being opened is

100 to 108, the forwarded data to the first value in the range will be sent to 4000. Subsequent

ports will be mapped accordingly; 101 will be sent to 4001, 102 will be sent to 4002, and so forth.

−

From the

Application Type

drop-down list, select the application type. If you do not know the

application type, select nothing.

Notes:

For easy identification, use the name of the application (for example,

Redwing Game Server).

Clicking

Back

returns to the

Allow device application traffic to pass through

firewall

page.

Note:

If only one port is required, enter the port number in the

From

field.

Note:

You can find the above information in the documentation provided by

the company that produces the application.

Adding Multiple Definitions to a Profile

Some application requires both TCP and UDP ports. In this case, you need to define additional ports to an

existing profile. You can add the definition of the profile only when it has not been added to the hosted

application list. If the profile is added to the hosted application list and you want to modify it, you need to

first remove it from the

Hosted Applications

panel.
