服务器防火墙允许端口80/TCP上的传出流量是否也允许端口80/UDP? [英] Does the server Firewall which allows Outgoing traffic on Port 80/TCP also allow on Port 80/UDP?

问题描述

在使用UDP协议的情况下，在端口80/TCP上接受传出流量的Windows防火墙是否也允许传出流量.

Is the Windows Firewall which accept outgoing traffic on port 80/TCP allow outgoing traffic also when we use UDP protocol.

在大多数情况下，防火墙仅控制端口号还是控制使用的协议?

Does a Firewall in most cases control the port number only or controls the used Protocol also ?

推荐答案

TCP和UDP端口完全不同.因此，TCP/80与UDP/80无关，但数量无关.从防火墙的角度来看，它们是完全独立的事物，具有独立的规则.

TCP and UDP ports are entirely different from each other. So, TCP/80 has nothing to do with UDP/80, except for the number. From a firewall's perspective, they are entirely separate things with separate rules.
