ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3

Services Overview

Examples of web servers that provide web services include the following: web servers

provide web pages, time servers provide time and date information, and game hosts provide

data about players’ moves. When a computer on the Internet sends a request for service to a

server computer, the requested service is identified by a service or port number. This number

appears as the destination port number in the transmitted IP packets. For example, a packet

that is sent with destination port number 80 is an HTTP (web server) request.

The service numbers for many common protocols are defined by the Internet Engineering

Task Force (IETF) and published in RFC

1700, Assigned Numbers. Service numbers for

other applications are typically chosen from the range 1024 to 65535 by the authors of the

application. However, on the VPN firewall you can select service numbers in the range from

to 65535.

Although the VPN firewall already holds a list of many service port numbers, you are not

limited to these choices. You can add additional services and applications for use in defining

firewall rules.

To define a new service, you must first determine which port number or range of numbers is

used by the application. You can usually find this information by contacting the publisher of

the application, user groups, or newsgroups. When you have the port number information,

you can add the new service.

Add a Customized Service

The following procedure describes how to add a customized service that you then can use as

an object for a firewall rule.

 To add a customized service:

1. On your computer, launch an Internet browser.

2. In the address field of your browser, enter the IP address that was assigned to the VPN

firewall during the installation process.

The VPN firewall factory default IP address is 192.168.1.1.

The NETGEAR Configuration Manager Login screen displays.

3. In the Username field, type your user name and in the Password / Passcode field, type

your password.

For the default administrative account, the default user name is admin and the default

password is password.

4. If you changed the default domain or were assigned a domain, from the Domain menu,

select the domain.

If you did not change the domain or were not assigned a domain, leave the menu

selection at geardomain.

5. Click the Login button.

The Router Status screen displays.
