Requirements
If you planning send packet over internet, then open port 9 on your router and forward UDP packets from it to 192.168.1.254 (any unused ip).
Also, you should add static ARP record on router (telnet command for Zyxel Keenetic Start):
After this all packets from internet to UDP/9 port will forward to 192.168.1.254 and acts like broadcast packets.
