Creates a rule in the network ACL with the specified rule number. Each network ACL has a sets of numbered ingress rules and egress rules. Priority rules depends on number: the rule with smaller number has higher priority.

Attention

The network ACL cannot have two rules of the same direction (ingres/egress) and the same number.

  • egress — Indicates whether this is an egress rule.

    • Required: Yes

  • PortRange — The port range the rule applies to. For TCP or UDP only.

  • Protocol — The protocol. A value of -1 or all denotes all protocols. If you specify all, `` -1``, or a protocol number (not TCP, UDP, or ICMP), traffic will be allowed on all ports, regardless of any ports or ICMP types or codes you specify.

  • RuleAction — Indicates whether to allow or deny the traffic that matches the rule.

    • Type: String

  • return — True is returned if the request succeeds, and an error otherwise.

    • Type: Boolean
