Use openwrt with zerotier as a gateway

[ganganrobert]

I want to use my router with zerotier as a gateway for other devices, I did settings as it mentioned in this https://github.com/mwarning/zerotier-openwrt/wiki ,but I get Ip address from my mobile isp. I can access to the 192.168.1.1, but not the gateway throw my router. Is it possible to have the same ip in mobile phone as a router ip?
