Cannot select specific tunneling address in connection manager

Hello community,

I already was in contact with the manufacture (MDT) of my IP interface (SCN IP 000.03) but was asked to post my problem here.

When connecting to my KNX bus, I cannot select a specific tunneling address in the connection manager (ETS 6.4.1 build 8718), although the connection works in general, however I would like to use one of the specific set up tunneling addresses.

The interface was set up with the application using secure tunneling and its tunneling addresses start from 1.0.252 up to 255, while the physical address of the interface itself is 1.0.1.

In the connection manager there is a field for using a specific physical address for connection, however as per documentation:

"The Individual Address of the currently used tunneling interface

Can only be set here for plain devices; for secure-capable devices the Individual Address can only be changed within the project where the device can be found"

But, where in the project I can setup the specific address to be used by the ETS when connecting to the KNX bus then?

Your help is appreciated, thanks a lot.

Regards,

Alexander
