CEL expression that specifies the match condition that egress traffic from a VM is evaluated against. If it evaluates to true, the corresponding action is enforced. The following examples are valid match expressions for public NAT: inIpRange(destination.ip, '1.1.0.0/16') || inIpRange(destination.ip, '2.2.0.0/16')destination.ip == '1.1.0.1' || destination.ip == '8.8.8.8' The following example is a valid match expression for private NAT: nexthop.hub == '//networkconnectivity.googleapis.com/projects/my-project/locations/global/hubs/hub-1'
An integer uniquely identifying a rule in the list. The rule number must be a positive value between 0 and 65000, and must be unique among rules within a NAT.
