Is it possible to configure Apache to not listen on port 80 when connecting from localhost, but allow the connection on port 80 from an external IP?

2you can block with iptables access from localhost to port 80 while allowing all other traffic, what are you trying to achieve?– LinuxDevOpsApr 3, 2014 at 17:42

Because I need the port 80 on localhost released to another application that also uses port 80, but this application lets not change the door Need to somehow free up port 80 to localhost and I need that Apache continues to function externally. Sorry my english– user2577532Apr 3, 2014 at 17:47

You can do this with multiple listen directives
Listen 192.0.2.1:80
Listen 203.0.113.1:80
Multiple Listen directives may be used to specify a number of addresses and ports to listen to. The server will respond to requests from any of the listed addresses and ports.
On a CentOS System I have to hand
Listen 192.168.254.16:80
netstat -tnlp | grep :80
tcp 0 0 192.168.254.16:80 0.0.0.0:* LISTEN 15014/httpd
telnet localhost 80
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
Connection Refused generally means nothing is listening which can be seen from the netstat output.
Listen 80
netstat -tnlp | grep :80
tcp 0 0 :::80 :::* LISTEN 15135/httpd
telnet localhost 80
Trying ::1...
Connected to localhost.
