Networking over internet

When, for instance, activating a special event callsign it is possible to network multiple DXLog stations over the internet.


The most secure way for remote networking is to rely on a VLAN (virtual LAN) software. There are several available such as:


Each VLAN solutions have their own particular set up which is covered in their respective documentations.
With a VLAN solution, all DXLog configurations are the same as when operating in a regular LAN.

One weakness with connections over the internet (a.k.a. WAN), including VLAN solutions, is that they are prone to packet loss.
Packet loss is disastrous to DXLog's (or any logger's) standard UDP networking.

It is therefore absolutely necessary to run ONLY TCP networking over a VLAN.

Hamachi is particularly popular since it is free for up to five computers. Thanks to the communications
architecture of DXLog, this translates into up to five geographical locations.

Since DXLog is able to mix TCP and UDP networking, a distributed station set up should be configured to rely on TCP
for the wide-area network and UDP for the local network at each station location. Below you will find the station
set up for the Swedish HQ station SE9HQ in the 2019 IARU HF Championship. The cluster client was run
on SK3W-A which distributed spots to all stations over the network. inband interlock was used at the SK3W location.


Important to note:

  • For the server as well as the main clients, Server IP should be set to the server's VLAN IP address, not its LAN address.
  • The server should check both "Start networking server" and "UDP network broadcast for multiple stations".
  • The main clients should check both "Connect as network client" and "UDP network broadcast for multiple stations".
  • All other stations should check only "UDP network broadcast for multiple stations".
  • Interlock over VLAN does not work reliably because of packet loss.
Therefore, it is important to configure any interlock to only consider relevant operating positions,
which all must be local. Use the possibility to only consider named stations for the interlock in the software
interlock set up. Options|Networking|Software interlock "Custom station ID(s)"
  • For a large set-up with many stations connecting as clients to a central server you may overload the server if you also
distribute spots via all client-server connections. In this case, check the "No spots via client/server" option
on all stations and use local DX cluster connections via UDP at each location.

Port forwarding

If you are less worried about competitors or government agencies listening in on your contest data,
it is possible to route the traffic directly over the internet using port forwarding at the server.

Important security notice: This solution is not without risk. It offers no security or authentication.
Any DXLog station running the same contest configuration, knowing the URL or IP address and IP port of the
server can connect to the server station. There are no means to disconnect a station by force.

With a port forwarding solution, the following must be observed:

  • Server configuration
  • Only one of the stations should be configured as the server.
  • "Connect as client" should not be checked and "UDP network broadcast" should only be enabled if it is
used to communicate with other stations on the same LAN.
  • The PC acting as server must have a fixed LAN IP address. This is done either by manually configuring the
PC to use a fixed LAN IP address, or by setting up the router in the server's LAN to to always allocate
the same IP address to it.
  • The internet connection used by the server PC must either have a fixed public IP
address or use dynamic DNS. Otherwise clients will not be able to reliable connect over the internet.
  • The server's TCP/IP port (default 9888) must be forwarded to the internet by configuring the router
connecting the server's LAN to internet. Only TCP traffic should be forwarded.
DXLog UDP traffic is not carried well over the internet.


Example configuration for server for networking over internet


Example of port forwarding UI in router


  • All other stations
  • All other PC in the multi-station set up should be set up as TCP clients.
  • Over the internet, "Server IP" is either the public IP address of the server's internet
connection (e.g. or the dynamic DNS address (e.g.
Clients connecting over the internet does not have to enable UDP networking and should not enable a server.
  • A client may connect via UDP if it is on the same LAN as the server or a "master client".
A "master client" is a client that connects to the server using the "connect as client" option in
the networking set up panel. A "master client" can act as a UDP gateway which means that if
several computers on a LAN are part of the same multi station set up but the server is located
elsewhere, only one computer in that LAN needs to connect as a client and the rest can use UDP.
  • Software interlock is UDP-based and can reliably only be used locally. Never over the internet.


Example configuration of client for networking over internet


  • In a multi-station setting it is recommended to enable Options|Networking|Don't allow QSO logging if operator isn't logged
  • Make sure Options|Enable network is checked.
