ONFIGURATION

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

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. 

It is possible to administer the Gateway from four options:

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

2 Enable administration from a single Internet Host - Only the specified IP 

address can manage the Gateway. Any other users will be rejected.

3 Enable administration from a whole subnet - This option allows a 

number of users within a subnet to administer the Gateway.

4 Enable administration from any Internet Host - This options allows any 

host to access the administration pages.

To remotely administer your Gateway, enter 

 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.
