I have used this scrip before and works, but now with the new update 6.18 when I put the script via Terminal says this:
“input does not match any value of policy”
What I can do?
Thanks 
Try to remove the two instances of policy, i.e. the policy in
/system script
add name=HomingBeacon-Simple > policy=
ftp,reboot,read,write,policy,test,winbox,password > source=“# Dynamic DNS Up
/system scheduler
add comment=”" disabled=no interval=5m name=DDNS on-event=
HomingBeacon-Simple > policy=read,write,policy,test,password > start-time=
startup
policy=
read,write,policy,test,password source="#
Now works, Thank you very much!!
