Managed IPs numbers for one Address

I have one address connected to mikrotik interface with 16 managed IPs and i use nat in mikrotik the 16 IPs to internal IPs in my LAN . I tried to add more IPs to Mangaged IPs but it is not accpet .
how to solve this problem . or there is limitation on IPs .

Not sure if you were ever able to solve that, but an easy way to solve that is to do a managed route to your MikroTik. You can do a managed route for a full /24, and then just NAT inside of your router for that /24. That way you don’t need to assign multiple IPs to a node within ZeroTier.
