4.8 Access Control
Access Control allows you to assign different access rights to 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 for each group. Access rights can
allow or block for access specified TCP and UDP ports. For example:
Group Members Access Right Comments
Default - Allow 0 No access right (allow nothing)
Group 1 100-199 Allow (25,53,80,110)
Can browse(80), receive(110)
and send(25) email only
Group 2
