Here’s how to add a GCP firewall rule with the AH (authentication header) and ESP (Encapsulating Security Payload) protocols.
gcloud compute firewall-rules update "firewall-name" \ --description="firewall description" \ --priority "1000" \ --target-service-accounts="service-account@gserviceaccount.com" \ --destination-ranges="10.0.0.0/8" \ --rules 50,51,tcp:80,udp:1000 |
There is no need to add protocols for AH and ESP. Just the port numbers.
