Hi sophocles77,
The main issue is whether it is safe to allow "core networking" in firewall for public network,right?
Core networking is a group under which many windows services create their rules. So the port they are listening to vary based on the rule. For example DHCP service listen at port 67/68 so those would be added in DHCP service rule. There are some rules for
ICMP traffic so port is not applicable to them. For more information what each rule is meant for, you might want to take a look at the description part of it.
If you disable these rules, correspoding services wont be able to receive packets.
I have checked my own machine and it is enabled for "Core Networking" by default.
Best r
