GCP SDK Firewall Rule AH and ESP
Here’s how to add a GCP firewall rule with the AH (authentication header) and ESP (Encapsulating Security Payload) protocols.
<pre lang="bash">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.
