Block Gtalk and other messengers
I have recently installed Pfsense in my office and I want to block Gtalk so that nobody can chat using Gtalk either using the desktop software or within their gmail.com accounts. Can anybody suggest me how to block it?
To block gtalk and chat from gmail.com, I have setup DNS forwarding for talk.google.com, talk.x.google.com and chatenabled.mail.google.com and forwarded all the three domains to my local IP. This has disabled Gtalk from both web and messenger.
