Port Forwarding
Port forwarding allows selected servers running on the LAN side of the router to be accessed from the
WAN side. Requests from the WAN to a configured TCP or UDP port will forwarded to the selected IP
address on the LAN.
In order to provide such access, your SpeedStream router may be configured to forward certain inbound
traffic from the WAN-side to a specified LAN-side server. WAN-side connections have knowledge of,
and hence direct access to, only the known public IP address associated with the WAN-side interface of
your SpeedStream device.
This methodology is commonly referred to as port forwarding, and is implemented by means of a
Network Address Port Translation (NAPT) operation.

Port Forwarding Configuration Options

Select service by name:
You can select either a service name or protocol to which the port forwarding rule will be applied.

Select protocol:
To apply the port forwarding rule to a protocol, select TCP, UDP, ICMP or GRE from the Protocol
list.
Enter port range for TCP/UDP protocol:
Required if you selected the TCP or UDP protocol, you must also define either a single port or range
of ports.
Redirect selected protocol/service to this router/IP address:
Select this option if the server for the previously specified service or protocol resides on the router.
Redirect selected protocol/service to IP address:
Select this option if the server for the previously specified service or protocol resides on a host
located on the LAN. In this case, you must specify the IP address of the host on which the server
resides. (This option is usually selected.)
