Configuring the Firewall
The WTM652 provides a firewall to protect the computers on your home network
from unwanted access. The firewall provides the following features:
• Virtual Server Support: if you have a server on your home network that you
want to make available to the general Internet, you can configure a virtual
server. The firewall passes requests from the Internet to the designated
computer on your home network.
• Client filters: you can use client filters to block computers on your network
from accessing the Internet (or certain services) during specific days and
times.
• MAC Address filtering: allows access to the wireless network only by com-
puters specifically authorized to connect.
• Ping blocking: ignores ICMP (Ping) requests from the Internet.
