4.8 Access Control
Access Control allows you to assign 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 the members of Group 1, 2 and 3. The others are all members of the Default Group.
Second, you have to assign the access rights of each group. Access rights can allow or block
users to access specified TCP and UDP ports. For example: If you want IP addresses 50-99
to block access to port 21 and 119, you would insert
50-99
into the Group 1 members box.
Change the Ports drop-down box to
Block
, and type
21,119
into the box to the right of the
Block box.
