68CHAPTER 5: GATEWAY CONFIGURATION

This feature is enabled by clicking on the check box so that a tick can be seen and then select Apply.

3Com recommends that you leave this disabled.

Disable Firewall The Gateway contains a firewall that detects attack patterns used by hackers on the Internet and once detected will block their access to your network. When an attack is detected a log entry will be generated and the Alert LED will be lit for 2 seconds. The firewall will block Internet access to all unused TCP and UDP ports.

The Firewall is disabled by clicking on the check box so that a tick can be seen and then select Apply.

3Com recommends that you leave the firewall enabled.

Enabling Remote Administration

It is possible to administer the Gateway from four options:

1Disable Remote Administration - This option is set as default.

2Enable administration from a single Internet Host - Only the specified IP address can manage the Gateway. Any other users will be rejected.

3Enable administration from a whole subnet - This option allows a number of users within a subnet to administer the Gateway.

4Enable administration from any Internet Host - This options allows any host to access the administration pages.

To remotely administer your Gateway, enter http://xxx.xxx.xxx.xxx:8000 in the location bar of the browser running on the remote computer, where xxx.xxx.xxx.xxx is the Internet IP address of the Gateway. You may then login using the administration password.

Your Internet IP address can be found at the bottom of the screen. See Figure 55.
