Hi,
I'm having trouble accessing my webinterface through VPN set up by a client. Also having trouble accessing the programming interface via LM in ETS when connected to VPN.
The IT department at my client asked me what ports that needed to be opened up.
I said TPC 80 or 443 and UDP 3671.
Anything else that needs to be opened?

Yes, it's TCP 80/443 for the web interface and UDP 3671 for KNX tunneling. Access to the KNX port is blocked from public IP ranges. In some rare cases internal networks are misconfigured to use public IP ranges. Private ranges are defined as follows:
10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
192.168.0.0 – 192.168.255.255

Hi, thanks for the reply.
That's strange, I've asked for 80 and 443 TCP and 3671 UDP. And the LM is on range 172.22.74.xxx. Are there any other issues that might stop my connection?

Hello asgeirsb.
Are you Shute that you entered the correct subnet mask and gateway?

When I think about it I am actually not sure I did. I need to contact IT again and ask them what is the correct subnet mask and gateway. I just assumed the standard 255.255.255.0 and 172.22.74.1 gateway
