Configuring a specific rule on Sophos XG125 Firewall

Question

How can I configure a specific rule on the Sophos firewall, e.g. I want a specific public IP address 8.8.8.8 from the internet to be the only public IP address allowed to access a server 182.168.1.1 on my LAN? 
 
 Thanks.

Aaron, 
 for the DNAT rule:

 inside the Source area rectangle, in the "Allowed client networks" put only the source ip you want to allow.
