I have installed zerotier on one raspberry exposing an avahi service discovery. Once zerotier is running , the service cannot be discovered anymore by other local area network devices. These devices have no zerotier installed (they are iot devices, it is not possible to install zerotier on them)
as additional information, my raspberry (running zerotier) is connected on the home router using ipv4 :
eth0 : UP,BROADCAST,RUNNING,MULTICAST,
while the iot devices are connected to the raspberry using ipv6 :
wpan0 : <UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>).
I have tried to configure a route following the " Route between ZeroTier and Physical Networks" instructions page, with fd00::/8 as destination address (which is the subnet of my iot ipv6 devices) without any success…
Is there any way to “exclude” wpan0 interface from the zerotier vpn ?
the avahi-daemon config was conf as default, without specifying any interface. That means that avahi will advertize on all local interfaces “unless point-to-point” interfaces, which is the case of the wpan0 one.
So, I changed the settings of the daemon, adding wpan0 on the allow-interfaces param.
