Problem with Routing function and programming devices

[buuuudzik]

Routing on LM can only be used for group communication (this is done for security reasons). If your LM is connected to KNX TP you must set connection mode to TP-UART. Keep IP features enabled and routing will work as well. For TP device programming you need to connect to each LM via tunneling.

So I must change connection mode on LM to do this? On TP-UART mode does filtering works?

But IP Routing not working also for group commnication! When I replace LM via MDT router with same configuration all is good but on LM with IP Routing configuration communication is only on IP side but not on TP. On TP-UART it is. So I think there is some very important bug in IP Router.
