Eero pro 6

Can someone please help me to figure out why my Facebook messenger will not send messages to anyone in my home who are on the same network as me?! Also I can’t log into Facebook when connected to my WiFi but if I turn on mobile data I can log in straight away. I have deleted and reinstalled the messenger app , this seemed to work but not even 24 hours later it’s happened again!! It’s to do with this network or the eero, the messenger problem started to happen after the eero updated but for some reason I’ve never been able to log into Facebook when connected to this WiFi but can log in via mobile data! Please help! I’ve tried all the usual steps of rebooting etc turned security off on the eero app tried all the basics to no avail!

This sounds like NAT loopback to me. This is where any communication from a device connected to the local router that goes out to the internet and then tries to go back into the local network is blocked by the rout. TalkTalk considers this to be a security vulnerability. I can't be certain if this applies to an Eero or not, as I have never used one, but it does on all other TalkTalk routers.

The way around this normally is to use the destination IP address of the other device that is locally connected to the router (e.g. its 192.168.1.x address) rather than the router's WAN or public IP address.

I have no idea how Facebook Messenger works in this respect. You will probably need to speak to their technical support about this unless you can create "local" contacts for these people.
