I am just a lay person but I tend to think about FTL travel in terms of traveling faster than the speed of sound. There is a sight dimension in which we can see the object before we hear it. Is there another dimension that we can observe the object traveling FTL?
if server a is behind a nat, it first needs to send out a message to server b this will open a random port for typically 60 seconds automatically. Then another message will need to originate from server a within the 60 second time period in order to keep the port open.
