I want to setup QoS (BWM in zyxel's term) to give my obi100 (a SIP phone adapter) priority. Instead of messing with the ports or protocol, I think the easiest way is just to tell the USG20 to give high priority to any traffic to/from the obi.
I can't figure out how to define an object based on a device's MAC address. It seems to only accept IP for objects, but IP can change due to DHCP.
Any ideas?
