Re: How do i block google talk on a Firewall ? posted 01/25/2008

I don't think that works. simple because if you take out
talk.google.comthere are several other talk servers, its not good
enough to track all of
them and block because you might eventually block gmail itself. The only way
to do it would be using IPS. I guess this was some time last year i had
posted a solution for blocking the same on netpro, more people had
contributed to the same.
