I have a device from my ISP, which is configured as a bridge, and an Asus RT-AX55 router with 3 machines connected to it.
For some reason the router sends STP packets every 2 seconds to at least one of my machines. I'm betting it's sending them to all but I did a Wireshark trace on only one.
This is what the packet looks like:
The source and destination ports were empty.
I have NO idea why the ROUTER would send STP packets and in its configuration there isn't any mention of STP, so I can't even turn it off. And, like I said, it's the only router in the network, so I don't think I need those and would, at least, like to block my Windows machines from receiving them but with no ports or protocol I don't know what kind of firewall rule to add.
How I can disable the STP on the router and bonus points if anyone knows what firewall rule I can add to Windows Firewall to block such incoming packets.
