Configuring Google Cloud firewall rules
You must open incoming port(s) to access FortiGate over the Internet.
HTTPS is the first necessary port. Other ports are optional depending on what features you enabled. See FortiOS Ports.
To configure Google Cloud firewall rules:
- Go to the virtual public cloud where the public-facing subnet belongs for the FortiGate.
- Select Firewall rule, then Add firewall rule if the required port is not open.
