Public IP && Route Via Zerotier

[microdockman]

When the external public IP address changes, Zerotier's ''Route Via Zerotier'' function becomes invalid and can be restored by restarting openwrt. Since I use a dynamic public IP address, I have to restart openwrt several times a day to restore ''Route Via Zerotier'' function

0 2,7,12,17,19 * * * sleep 70 && touch /etc/banner && reboot
This is the current setup
