If your rule involves the website, that is, the destination request port. If it is 80, then the corresponding port corresponding to port 53 should be considered to be allowed to pass, because 53 corresponds to the packet destined for the “domain name resolution server” and is used for the domain name (eg, IP address (eg, ) Corresponding, it must be opened!
