Creating your new traffic flows

Now that you've created the new zone (CUSTOMER-PUBLIC), you'll need to configure policies to control the network traffic flow. The first one configured allows all traffic within the CUSTOMER-PUBLIC zone. The second allows all traffic from CUSTOMER-PUBLIC out to the public internet, while the third flow allows only SSH and PING traffic from the public internet to CUSTOMER-PUBLIC, and drops the rest (as the default action is drop).
