Security
The Security page is used to control access to the GCN1000.
Software Installation
Overview
IP and MAC Filters control access to the GCN1000 based on the IP and/or MAC addresses of the
•
computers attempting to access the system. If any fi lters have been confi gured, they appear in the
IP Filter and/or MAC Filter list boxes.
The Login string lets the Administrator specify a string that users must include along with the
•
GCN1000’s IP address when they access the GCN1000 with the Java Applet. For example, if the
IP address were 192.168.0.126, and the string was abcdefg, the users would key in the following:
192.168.0.126/abcdefg
Users must include a forward slash and the string along with the IP address when they log in. For
security purposes, we recommend that you change this string from time to time.
Filtering
To enable IP and/or MAC fi ltering, a check mark in the IP Filter Enable and/or MAC Filter Enable
checkbox enables the fi lter. There are a maximum of 100 fi lters allowed for each option.
If the include button is checked, all the addresses within the fi lter range are allowed access to the
•
GCN1000; all other addresses are denied access.
If the exclude button is checked, all the addresses within the fi lter range are denied access to the
•
GCN1000; all other addresses are
allowed access.
