This article shows the configuration to protect a server from attacks from countries the user has no business with.
First, create an address object:
Go to Policy&Object -> addresses and then select 'create' and 'new address'
Name: Choose a name
Type: Select 'Geography'
Country: Select the country to block
Do this for all the countries to block.
Then, create a group for these countries that need to be blocked.
Select 'create' and 'new address group'
The last thing to do is to create a policy.
Go to Policy & Object -> IPv4 Policy
Create a policy that blocks the traffic from the countries to your resources (like servers in your DMZ) that need to be protected.
Once this rule is created, the traffic from that countries will be blocked (this is to protect the server only, it does not block the internet).
