저와 제 형제들은 컴퓨터 게임 GTA 온라인을하고 있습니다. 우리는 모두 동일한 로컬 네트워크에 연결되어 있습니다.
그러나 때때로 연결 문제가 발생합니다. 이제 공식 Rockstar 사이트 에서 라우터의 일부 포트를 잠금 해제 / 전달하는 데 도움이 될 것이라고 읽었습니다 .
그러나 단일 컴퓨터의 경우 이것은 나에게 의미가 있지만 다음 두 포트 전달 규칙을 정의하면 라우터가 들어오는 패키지를 어떻게 처리합니까?
You can see that I forward for example port 80 to computer Black and Black2. Will computer "Black" and computer "Black2" receive all incoming packages on port 80 of the router now, and other computers won't receive anything?
And does computer Black also receive the packages which are targetted to Black2, or only his packages?
How does the router know the correct target?
Packets received at port 80 etc. are going to be forwarded to ONLY ONE internal pc, either Black or Black2.
Will computer "Black" and computer "Black2" receive all incoming packages on port 80 of the router now, and other computers won't receive anything?
Incoming packets on port 80 of the router's external interface are going to either Black or Black2. It is hard to tell which one, it depends on the order in which the router internally processes the rules. The fact that Black comes first in your web management does not necessarily mean that its rules have a higher priority than those regarding Black2. One thing is correct, though: other computers won't receive anything.
Does computer Black also receive the packages which are targetted to Black2, or only his packages? How does the router know the correct target?
This is the crucial point: there is no way for the router to tell whether a packet is intended for Black or Black2. It cannot discern between them and is probably going to send all of them to Black or Black2. It can also happen that some of them go to Black and some go to Black2, but those won't be the "right" ones. Since you are forwarding more than one port, it can happen that packets incoming on one port are going to Black and packets incoming on another port go to Black2. There is no predicting this since you gave the router ambiguous directives.
What can you do?
You have to take control over which packets go where. I see two ways.
