IMPORTANT: Some routers let you specify both external and internal port
numbers. This is useful, for example, if you have multiple K4 servers on a
single local network (LAN). They all use 9204 as their internal port number
but you must assign a different external port number and port forwarding
instruction to each server K4. Clients specify the external port number, and
your router associates it with the desired server radio. (Port-forward the
external number to the IP address of the target K4.) The simplest setup is
one K4 on a local network using 9204 as both the internal and external port
number.
Specific Example (Xfinity Router, one server K4): Xfinity provides a
smartphone app for configuration of all services, including router setup.
Your router may have different, though equivalent, instructions. (1) Run the
Xfinity app and log in. (2) Tap the WiFi icon at the bottom of the screen,
then tap "View WiFi equipment" (even if your K4 is directly connected to
the router). Then tap "Advanced settings," followed by "Port forwarding." If
any port forwarding is already set up, it will appear on this screen. (3) Tap
"Add Port Forward." (4) At the top of the screen you'll be prompted to
"Select the device…," with a pull-down menu. Tap the entry in this device
list that corresponds to the K4. NOTE: The K4 may be listed as: "K4-
[SerialNumber]," "Generic Brand Linux PC," "Aaeon Technology, Inc," or as
the IP address shown in the K4's "IP Address" menu entry. (5) Enter 9204 in
the "Port Number" box, and make sure "TCP/UDP" is selected in the
"Protocol" box. (6) Click on "Next." This should complete the process.
K4 Server Settings
The following steps are only required if you wish to make your K4 accessible
as a server radio for use by yourself or others. Once port forwarding and
server setup are completed, no further action is needed on the server side.
Clients will be able to access your K4 anytime it is powered up and has an
Ethernet connection.
