> Yes they all support punching holes, in fact, I’m punching holes right now, otherwise I won’t be able to reply. But if you don’t punch, then there’s no hole. That is not what is meant by "hole punching": > Networked devices with public or globally accessible IP addresses can create connections between one another easily. Clients with private addresses may also easily connect to public servers, as long as the client behind a router or firewall initiates the connection. However, hole punching (or some other form of NAT traversal) is required to establish a direct connection between two clients that both reside behind different firewalls or routers that use network address translation (NAT). * https://en.wikipedia.org/wiki/Hole_punching_(networking) https://en.wikipedia.org/wiki/Hole_punching_(networking) * https://en.wikipedia.org/wiki/Port_Control_Protocol https://en.wikipedia.org/wiki/Port_Control_Protocol * https://en.wikipedia.org/wiki/Internet_Gateway_Device_Protocol https://en.wikipedia.org/wiki/Internet_Gateway_Device_Protoc...
