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 == 'https://networkconnectivity.googleapis.com/v1alpha1/projects/my-project/global/hub/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.
