. However, when the packet arrives at NAT (210.21.12.140: 5000), Nat will not know whether to send the packet to a (192.168.0.4: 5000) or D (192.168.0.5: 5000 ). Obviously, this packet can only be discarded. This is enough to prove that iptables has a port restriction attribute.Therefore, iptables is a genuine elastic Ric Nat. Appendix:1. Stun stands for simple traversal of UDP through NATs, so all the Packets involved in this article are UDP packets.2. Although this article analyzes iptables in
