NAT rules
Network Address Translation (NAT) allows you to translate IP addresses and ports for incoming and outgoing traffic.
It performs translation between private and public IP addresses, allowing private IP networks to connect to the internet and hiding the internal network behind the public IP address.
Note
Firewall rules allow or drop traffic entering and exiting the network. NAT rules translate IP addresses for traffic the firewall rule allows.
So, you must create firewall rules even if you've created NAT rules.
