Block Teamviewer in ASA 8.4(2)

According to the information I could find about this product, it makes an initial connection to the servers at teamviewer.com before the user can do anything else.  I would start by putting in an access-list blocking the site.

Server:          69.56.222.10

Address:     69.56.222.10#53

Non-authoritative answer:

Name:     teamviewer.com

Address: 46.163.100.220

I found this information on IPTools.com for DNS resolver for the url.  You can do this a little esier if you had a websense server for content filtering, but I know they are a little spendy.

Let me know if this helps.

Block Teamviewer in ASA 8.4(2)

thanks Kimberly for your answering, but is it possible to do it through using regular expression (regex) to close the teamviewer ?

I am not sure about doing this with REGEX, that is something that I don't know much about.  Worth a test to deny it on the firewall.  Do you have any content filtering products for filtering out the internet?  If you do, that would be the place to start, but if you don't then through GPO you can have the client uninstalled from the workstations or start restricting the user's administrative rights on their workstations.

Just offering other options for getting this done.

Thanks,

Kimberly
