BACNET IP and IP filters comm

[ALEJANDRO]

So, if, for example, I have 200 group addresses common to LM_1 and LM_4, and I only want communication between 5 of those 200 group addresses, the best thing I can do is:

- LM_1 > LM_4 ->> in LM_1 KNX connection >> IP > local > DST group policy >> Drop..... >> Group address list >> enter the 150 group addresses >> OK

- LM_4 > LM_1 ->> in LM_4 KNX connection >> IP > local > DST group policy >> Drop..... >> Group address list >> enter the 150 group addresses >> OK

Could this be a solution to allow communication only between 5 group addresses stored in LM_1 and LM_4?
