Access Control
Access Control allows you to assig n different access rights for different users.
First, you have to divide users into different groups. Users are identified by their
IP addresses. You can assign members to Groups 1, 2 and 3. The others are all
members of the Default Group. Next, you have to assign the Access Right of
each group. Access Right can allow or block users access to specified TCP and
UDP ports. For example:
Group
Default
Group 1
Group 2
Group 3
