LM - "IP Tunneling" "IP Routing" and "Multicast IP"

[joaodaniel.pereira]

Hi,

I'm trying to understand the concept of "IP Tunneling" "IP Routing" and "Multicast IP" for LM

If I have 2 devices on the same VLAN imagine: 192.168.28.01 and  192.168.28.02:
     the device *.01 mode: TP-UART,  knx: 15.15.1 and multicast 224.0.23.12     and 
     the device *.02 mode: IP-Tunneling : router: 192.168.28.01 (device 01), knx: 15.15.2 and multicast 224.0.23.12

Whit this I can send KNX frames from one to other with success and it's possible to update remote values... but
ETS return error programing device 01: "FAILED TO CONNECT TO 1.1.1"  .. if I remove the power of device 02, the programming is updated with success! 

If I have a company with multiple VLANs, it's possible to connect all the to appear on ETS , to program devices from 1 vlan to others ? 

Thanks.
