I have a Century Link C3000Z modem bridged to an Orbi router. In the modem, I set the IPv4 firewall as medium and unchecked all the X-box settings as well as anything gaming as we don't have or use an X-Box. The system log in the CL configuration fills up with entries like the following multiple times a minute ..mac address is the mac address for the modem as well as the SRC IP.

02/05/2024 04:08:11 AM Firewall Firewall DROP XBox:IN=br0 OUT=ppp0.1 MAC= SRC=192.168.0.3 DST=1.0.0.1 LEN=64 TOS=0x00 PREC=0x00 TTL=62 ID=0 DF PROTO=TCP SPT=53009 DPT=53 WINDOW=65535 RES=0x00 SYN URGP=0

Sometimes the DST is: DST=205.171.3.25 WINDOW IS SOMETIMES 29200 ID and SPT change with each entry

Can anyone explain why these are appearing.
