Keep KNX connection mode TP-UART and make sure that IP features are enabled on both LMs. Make sure that both devices have the same Multicast IP (default is 224.0.23.12). It's also highly recommended to enable encryption by setting the Backbone key and enabling Only secure communication. Keep in mind that you won't be able to use LM for KNX device programming in this mode.
