How to ulogd log & print all connections from a certain mac

I have several devices that I have blocked access to wan by just simply blocking port 0-65535 for all protocols.
these devices have to see the internet to be able to be configured through the app.
I would like to log all ports and see where they connect to for this one specific mac address.

I have found this:

Mar 13 15:03:57 openwrt ulogd[21765]: [NEW] ORIG: SRC=172.18.0.227 DST=1.2.3.4 PROTO=TCP SPT=57534 DPT=443 PKTS=0 BYTES=0 , REPLY: SRC=1.2.3.4 DST=5.6.7.8 PROTO=TCP SPT=443 DPT=57534 PKTS=0 BYTES=0
Mar 13 15:09:00 openwrt ulogd[21765]: [DESTROY] ORIG: SRC=172.18.0.227 DST=1.2.3.4 PROTO=TCP SPT=57534 DPT=443 PKTS=9 BYTES=3371 , REPLY: SRC=1.2.3.4 DST=5.6.7.8 PROTO=TCP SPT=443 DPT=57534 PKTS=8 BYTES=1301

but I am not sure on how to configure it so that it logs all ports to all destinations for one mac only.
