4.3.3 MAC Filtering
The MAC Filtering page allows you to specify PCs that must not have outgoing access to the WAN (Internet).
These PCs can still communicate with each other on the LAN, but requests sent to WAN addresses will be
blocked. The PCs are "filtered out" based on their MAC address.
Enter the MAC Address.
Click the Add MAC Address button.
4.3.4 Port Filtering
On the Port Filtering page you can enter destination ports (applications) to which your LAN PCs should not
connect. Connections that your LAN PCs want to establish with these ports are blocked. For example, you
could block access to worldwide web browsing (HTTP port 80) but still allow email service (SMTP port 25 and
POP3 port 110).
To enable port filtering, enter the
Start port
and
End port
for each range (to block only one port, set both
Start and End ports the same).
Select its
Protocol
form the drop-down list and check the
Enable
box.
Click the
Apply
button.
