ZeroTier tries to connect on every interface by default, and that makes me mad. I found a solution to blacklist interfaces, by editing /var/lib/zerotier-one/local.conf (you may need to create one, this path works on my machine):

1
2
3
4
5
{
	"settings": {
		"interfacePrefixBlacklist": ["ibgp", "dn42"]
	}
}

By this these interfaces are finally not crowded with zerotier requests.

Rename Tunnel Interface

Edit /var/lib/zerotier-one/devicemap:

1
networkname=iface

Don’t forget to service zerotier-one restart after editing.
