Memblok port di proxy squid

Procedure to block a port

First open /etc/squid/squid.conf file
# vi /etc/squid/squid.conf
Locate your ACL section and add configuration directive as follows:
acl block_port port 1234
http_access deny block_port
http_access allow all

If you just want to skip a particular IP (192.168.1.5) try as follows:
acl block_port port 1234
acl no_block_port_ip src 192.168.1.5
http_access deny block_port !no_block_port_ip
http_access allow all

Close and save the file.

Restart squid proxy server:
# /etc/init.d/squid restart
