Teamviewer 10 stops working after about 1 minute using a SonicWall TZ-215.

I have Teamviewer 10 Premium and a Sonicwall TZ-210. Teamviewwer works for about one minute on the internet then disconnects.
On the internal network I have no issues. I only have issues if over the internet.

I have removed the SonicWall TZ-215 from the network and Teamviewer 10 works correctly.

I wasn't using IPS but turned it on and disabled the function for Teamviewer and that made no difference.

Do you have a block rule for TV in Sonicwall or application control enabled?  If yes, then disable the application control (uncheck it) then test it again.  If not, then create a rule and allow (disable the block) in TV.

Also, have a look at Port Forwarding the Sonicwall for Teamviewer and apply the same port forwarding rule in your Sonicwall model (steps may be different).

I had previously disabled TeamViewer in the applications control area with no change.

The Teamviewer site says "In general, TeamViewer will always work if surfing on the Internet is possible. Hence, no firewall configuration is required.

As an alternative to port 80 HTTP, port 443 HTTPs is also being checked. In addition, it is also possible to open only port 5938 TCP on the outgoing side (required for mobile connections). Data traffic should then be able to pass through on this port without any problems."

I read that as I only need 5938 open is connecting with a mobile device.
