On my pfSense I run a wireguard server for remote access when I travel. In my house are 7 Chromecasts (don’t judge, I like them).
Normally I can’t see or cast to the Chromecasts when I have wireguard enabled but today I was able to both see and cast to 3/7 Chromecasts from 2,000 miles away on cellular when using the wireguard VPN.
So now I’m curious. Why can I suddenly see 3 of them and why can’t I see the other 4?
All of the Chromecasts are hardwired with Cat5e and powered 24/7 so it’s not like the other 4 we’re off. The firewall rules for wireguard are a basic allow all outbound. Avahi is not enabled for the wireguard interface. And the wireguard config is a full tunnel.
Any ideas why I can’t see the other 4 Chromecasts?
