VPN connection to Homelynk

[david.dumont]

Hi,

after an installation of a Homelynk at a customer, i need to reprogram some KNX equipements for a very little thing.

is it possible to create a VPN connection to a Homelynk to be able to program from a distance with ETS ?


Best regards, David Dumont

Yes, for sure this is possible. I don't know precisely how looks the configuration but generally you can do this with:
- static IP adress or DDNS,
- router which can be the VPN server e.g.  Mikrotik and PPTP server.
- you must send all traffic to client.

I know this because I had such solution on one building. Maybe there was some lags and I didn't tried program some much advanced devices but basic yes and this worked good

Maybe there is some much experienced user on this forum which can tell how this configuration can looks...

Sure. Just do a port forward of port 3671 from the internet facing router and to port 3671 on the Homelynk/LogicMachine device. This is usually done under NAT / Port Forwarding settings in the router.

Then just add the public/outside IP of the internett router as the IP/KNX adapter in ETS and you can program like you where on-site.

By doing so, be sure to disable the port forwarding after, otherwise your KNX network will be available to everyone sniffing the address.
Using a VPN capable modem is a better choice. Or some openvpn client/server so you have a secure connection between your PC and the remote site.
