Zone Alarm Settings and Traffic Question

[Plorp]

I've used ZoneAlarm for quite some time now and about 1.5 months ago reinstalled Windows and ZA. As far as I'm aware, I used the same settings as I always have, but checked the Firewall log the other day for probably the first time since reinstall and noticed traffic I hadn't ever seen before. Most of it seems to be multicast traffic from devices like Xbox One and Smart TVs on my network. Like, I'll see incoming traffic from them going to 224.0.0.1, 224.0.0.251 and 239.255.255.250. on ports 5355, 5355 or 1900. I also see traffic from my computer's IP directed towards my router and 224.0.0.251 on port 5353. From what I have read this is normal traffic when devices are announcing themselves and trying to find others, but I haven't seen multicast traffic in the logs before. I am also seeing traffic from 0.0.0.0:68 directed to 255.255.255.255: 67. According to the more info page, this is a DHCP request for authentication and Zone Alarm settings blocking it. Seemingly related I am seeing traffic from my computer to 192.168.1.255(I think this is also the router) on port 137. The more info page says this is my computer attempting to renew its IP and Zone Alarm is blocking it. Also, I seebtraffic from my computer to 192.168.1.255 on port 68. The Zone Alarm more info page says this is blocked NetBios. Finally, I am seeing traffic from my router 192.168.1.1 adressed to port 80 on my computer. If it helps, I have Trusted and Public Zones set to high. IIRC I have always had them set to high and have never had to manually add IPs to zones. Is there some setting I'm missing that is causing what I'm seeing in the logs?
