Great video! Networking always seems complex to me, but this video really clarifies a lot of things. But at 4:27, how would the gateway know whether to translate port 8080 or not? Like, why would it not translate for port 80 (the orange line), but would do for port 8080 (blue line)? Also, after the translation, both blue and orange lines are now port 80. Then how would the gateway know which internal server to route to (since they're both port 80)?
