how to provide Public static ip to the client

i have a question to all expert im new to this mikrotik world, how can i provide public static ip to the client.

for example my isp give a 2 public static ip let say 122.49.208.110/30 <<< connected to my port1 as my wan port, so i have 1 more public ip 122.49.208.109

and then my client connected to 2nd port which is private ip let say belong to 10.10.10.o/24 network so what if my client needs static public IP is there any config to trick this scenario? hehe

thanks thanks
