Would you please tell me what the reason, will

PS: can Telnet server port 80,

CodePudding user response:

Firewall is only responsible for the "allow" and "reject" request to connect to port 100, you add the allow strategy, doesn't have anything to do with 100 ports open,
Only service program to run the listener port 100, 100 port is open,
