RE: Blocking GoToMyPC

It is my understanding that you can have the company block access for
you.

Q: Do I have to be a GoToMyPC Corporate account user to block access to
the service?

No. The Authorization Management Service is available for any
organization that wishes to prevent unauthorized use of the GoToMyPC
service. For companies who do not currently have GoToMyPC accounts but
who wish to block access using our Authorization Management Service,
please contact GoToSales () expertcity com.

Subject: Blocking GoToMyPC


What is the easiest way to block GoToMyPC?  I do not want employees
either working on their home machines from work, or opening up the
network by bypassing the firewall.  
I think from reading GoToMyPC's website the remote machine must login
into one of the servers, then the client connect to the GoToMyPC server
and the server relays commands to the remote machine.  Also I think I
read that GoToMyPC uses HTTP and other protocols that normally the
firewall allows through.  

One idea that we had was to put a phony DNS entry into our DNS server
for the GoToMyPC domain, to send that traffic to a non-existent IP on
our network.  Would this work?  What would be the major problems with
it?

What about disallowing access to any ip that on a reverse DNS lookup
falls into the GoToMyPC domain?

Thanks for your time,
Brandon
