Block or allow IGMP traffic (Home network, no router)
Windows 10 Home 22H2 OS Build 19045.4170
I'm using Windows Firewall Control and I have an allow/block situation I'm not sure about:
NAME: NT Kernel & System (System)
DESCRIPTION: Outbound rule for NT Kernel & System (System)
PROTOCOL: IGMP
DIRECTION: OUTBOUND
all local & remote ports and all local & remote IP addresses.
I allowed this rule another time but the protocol was ICMPV4.
*I'm running Windows 10 Home on my home desktop PC. No other PCs or devices (no router) are connected (other than a couple monitors & some USB related devices). Nobody else uses my internet, only my profile, and nobody connects anything.
Should I allow this or block it?
I just am confused about IGMP within a ethernet cable connected modem. I think it has something to do with switches?
