IP Filters
An IP filter is used to deny any specific computer from accessing the Internet
using the computer’s IP address. You can deny access by to specific services
by port numbers or by blocking all ports for the specific computer. To add a new
filter, fill in the fields above and click Apply to save the page settings. You can
block access to several of the most commonly used services by clicking an Edit
button in the IP Filter table at the bottom of the screen. This will copy the proper
settings into the IP Filter fields. You will only need to enter the IP address of the
computer to be affected by the filter (you can find this number by displaying the
DHCP screen under the Admin tab).
