Networking over internet
For particular events like when activating a special event callsign or running a HQ station in the IARU HF Championships, it is possible to network DXLog.net installations over the internet.
The simplest and most secure way to do this is to rely on a VLAN (virtual LAN) software. There are several available such as:
LogMeIn Hamachi https://www.vpn.net/ FreeLan http://www.freelan.org/ Player.me https://player.me/ ZeroTier https://www.zerotier.com/
But if you are not too 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.
To do this, the following must be observed:
- Only one of the stations should be configured as the server.
- "Connect as client" should not be checked and "UDP
- It is necessary that the PC acting as server has a fixed LAN IP address or port forwarding will fail.
- 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 IP port (default 9888) must be forwarded to the internet by configuring the router
- connecting the server to internet. Only TCP traffic should be forwarded. DXLog.net UDP traffic
- is broadcast and should only be used locally.
- All other PC in the multi-station set up should be set up as clients.
- Over the internet, "Server IP" is either the public IP address of the server's internet
- connection (e.g. 5.150.248.52) or the dynamic DNS address (e.g. hq.sm7iun.se). 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 as a client. A "master client" can act
- as a gateway via UDP 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 needs to connect as a client and the
- rest can use UDP.
- Software interlock over internet is not reliable. On the other hand there is normally no need for it.
