Google talk ports: 5222,5223,5060,8000
Site Address: google.com and chatenabled.mail.google.com
Our aim is to block Google talk session, at the same time he should be able to use gmail. How to do that ?
ACL (Access Control List) to block Google talk.
I have created an acl named "chat_block", and saved all urls (google talk URLs and ports) in this file "googletalk.txt" .
Copy and paste this rule below this line.
acl CONNECT method CONNECT
Chat block rule.
acl chat_block url_regex -i 'googletalk.txt'
http_access deny chat_block
Copy paste these line to googletalk.txt
Save and restart squid service
