What is general idea of this functionality?
I am trying to reverse engineer one configuration which I think is wrong but I am not sure.
Devices in question are AV automation server on one VLAN and home automation server (lights etc.) on another VLAN. AV server should send commands to smart-home server for lights and blinds and currently is not working.
Both VLAN are configured to have inter vlan routing and I confirm that routing is working fine.
Somebody setup custom service forwarding:
from: Any network, port 502 - To “IP address of smart-home server” again on port 502
So my question is: is there any sense to forward from one port to same port on different VLAN when inter vlan routing is working fine?
