Re: How to block google talk (gtalk) both web based and software

Google talk uses TCP/5222 and TCP/443 to "talk.google.com".

You can just create ACL to block TCP/5222 and TCP/443 to and from "talk.google.com"

How to block google talk (gtalk) both web based and software bas

I have also the same problem, I am using  firmware

1.2.0.9

I was able to block a URL for a Specific IP, or IP range,

the problem was that it only worked on http (port 80), if the user change the site to https  (port 443) it overide the rule and provides the access to the site (of course the site can be access by https also)
