4.5 Configuring the Router Access Control

The Router Access Control option allows a system administrator to give clients or groups of clients specific access rights to Internet services. To set up this feature, follow the steps below. We’ve also included a list of common service port numbers on page 37.

Note: We recommend that you define the LAN MAC-address to LAN IP-address relationships before beginning the process of configuring Router Access Control. Click the LAN MAC Address Control button to proceed.

1 Open the Gateway’s Advanced Setup screen by clicking the same-named icon at the top of the main interface window, click Router Access Control, and check the Enable box.

2 Divide users into different groups. Users are identified by their IP addresses. You can assign members in three special Groups. Any unassigned members belong to the Default Group.

3 Assign the access rights of each group. You can allow or block access to specified TCP and UDP ports and Internet services. The table below shows a sample.

Group	Members	Access Right	Definition
Default	-	Allow ()	No access rights
Group 1	50-99	Allow (80,110,	Can browse(80), receive(110)
		25)	and send(25) email only
Group 2	100-199	Block (21,144)	Cannot read newsgroups

Group 3	1-9,20	Block ()	Full access (block nothing)
