This section provides procedures for configuring the options on the Applications page.
Important: Most well-known Internet applications are supported by Application Layer
Gateways (ALGs). ALGs automatically adjust the gateway firewall to allow data to pass
without making any custom settings. We recommend that you test your application
before making changes in this section.
Configure Port Filtering Settings
{
XE "Configure Port Filtering Settings" \t
"See"
}
Use the settings in this window to configure transmission control protocol (TCP) and user
datagram protocol (UDP) port filters. These filters prevent a range of TCP/UDP ports from
accessing the Internet. You can also prevent PCs from sending outgoing TCP/UDP traffic to the
WAN on specific IP port numbers. This filter is not IP address- or MAC address- specific. The
system blocks the specified port ranges for all PCs.
