How to give equipment an external IP with MAC binding?

Question

Network administration

Such a situation, there is a provider, we bought 4 external IP addresses from him. They will be used in banquet halls for customers who need an external IP. The provider binds ip to mac-addresses. But the equipment is always different ... What are the ways to distribute a white address to clients? The client equipment must not be behind NAT. Calling the provider every time with a request to change MAC addresses is not an option)

Answer 1

Set the desired MAC on the client.
Or put your equipment and take the client to the demilitarized zone.
