Reference documentation and code samples for the Google Cloud Compute V1 API module Google::Cloud::Compute::V1::ForwardingRule::IPProtocolEnum.
The IP protocol to which this rule applies. For protocol forwarding, valid options are TCP, UDP, ESP, AH, SCTP, ICMP and L3_DEFAULT. The valid IP protocols are different for different load balancing products as described in Load balancing features.
Constants
