Symmetric NAT, the public network IP will change, which is equivalent to a multi WAN router. This kind of network must use trunking. This is the most difficult NAT to penetrate
Symmetric NAT
Has anyone tried using netclient with multiple Wan routers? I am not sure whether it is caused by symmetric NAT or multiple Wan routers, because I encounter a network environment, that is, symmetric NAT, and multiple public IP, and the public IP is constantly changing randomly. I guess it is because of this reason. I don't understand the workflow of netclient and the impact of changing public IP on it.
