Enter a Name If you chose Port Range Forwarding, or if you chose Add a new
name in the Application Name list for Single Port Forwarding,
enter a name to identify the application.
External Port, Internal
Port
For Single Port Forwarding, specify the ports to use. For
simplicity, the internal and external port numbers will often be
the same. However, different external port numbers could be
used to differentiate traffic of the same application type intended
for different internal servers, or to promote privacy through the
use of non-standard ports.
• External port: For single port forwarding, enter the port
number that external clients will use to set up a
connection with the internal server.
• Internal port: For single port forwarding, enter the port
number that the ATA uses when forwarding traffic to the
internal server.
The correct entries appear automatically if you choose a
standard application from the Application Name list for Single
Port Forwarding.
Start - End Port For Port Range Forwarding, specify the range of ports to use.
Valid values are from 1 to 65535.
Protocol Select the protocol(s) that can be forwarded: TCP, UDP, or TCP
and UDP.
IP Address Enter the IP address of the local server that will receive
forwarded traffic.
To ensure correct forwarding of traffic, local servers must either
be configured with a static IP address, or be assigned a reserved
IP address through DHCP. Use the Interface Setup > LAN
> DHCP Server page to reserve IP addresses. See Network
Settings for the LAN and DHCP Server (SPA122 Only),
page 29.
Enabled Check the box to enable this port forwarding rule, or uncheck
the box to disable it. Default setting: Disabled
