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 access rights to the members of Group 1, 2 and 3. The others are all members of the Default Group. Next, 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:
Group | Members | Access Right | Comments | |
Default | - | Allow 0 | No access right (allow nothing) | |
Group 1 | Allow (25,53,80,110) | Can browse(80), receive(110) | ||
|
|
| and send(25) email only | |
Group 2 | Block (21,119) | Cannot read net news(119) and | ||
FTP(21) only | ||||
|
|
| ||
Group 3 | Block 0 | Fully access (block nothing) | ||
