The Access Control feature allows the administrator to control Internet access by individual workstations (PCs)
The Access Control feature allows administrators to restrict Internet Access by individual workstations. The process uses "Packet Filtering" to block or discard data packets. You can apply the pre-defined filters, and optionally define your own filters. By default, filtering is disabled; no packets are blocked or discarded.
Selecting the Access Control tab will reveal a screen like the example below.
To use the Access Control feature:
![]() |
You can limit Internet access for ALL PCs without entering ANY workstation data, by applying restrictions to the "Everyone" group. |
To Set or Change restrictions for a Security Group:
No Restriction
|
No packets are blocked. Use this to create an "Unlimited Access" group, or
to temporarily remove restrictions from a group.
|
Block all access
|
Groups members cannot access the Internet at all.
Use this to create the most restrictive group. |
Use List Below
|
Enable or disable individual items as required. If set to Block, the
item will be blocked, and the group will NOT have access.
This table is ignored unless the Use List Below radio button is selected. |
This list shows all workstations (PCs) which have been defined. It is only necessary to define workstations in the following situations:
Name
|
Enter an identifier for this workstation. The name is case insensitive
(case is ignored).
|
Group
|
Select the security group for this workstation.
If you only wish to reserve an IP Address, and are not using the Access Control features, simply leave this at "Everyone". |
Hardware (MAC) Address
|
Hardware or physical address. On a PC, this is often called the Network
Adapter Address. You can use the Windows "Winipcfg" program or your LAN
management program to find this address. (By default, there is no Start Menu
item for Winipcfg so you must use the "Run" command or create your own
shortcut.)
|
Reserve IP Address
for this workstation |
Check this if you wish to reserve an IP address for this workstation. This
is useful if you have to provide the IP Address for other programs or
users.
If this is left unchecked, the following entry can be ignored.
|
Reserved IP Address
|
This relates to the entry above.
Enter the reserved address here. This MUST be within the range used by the
DHCP server (set on the LAN screen).
