I'm attempting to test udp hole punching. Right now I'm simply testing how my computer reacts behind a router.
If I send a udp packet from my computer to a server, it can reply back on the same port no problem.
However if I send the packet first from the server. It never gets through. Which I expect. Ok so then the home computer sends the packet to the server and the server sends a reply. It still doens't get through.
What type of NAT does that? And can udp hole punching defeat this type of NAT?
I'm sorry if what I say doesn't make sense. I'm a software engineer and my network knowledge is limited.
