Make TeamViewer a one-way connection?

[johnmalc]

Hi.

I have installed TV on my main machine (host) to try it and it seems to be what I want (to control a remote machine (client) that in turn controls a long distance network). However, after installing it on the remote machine I found that TV not only showed my main PC but allowed access to it. The firewall popped up to inform me, but after I temporarily allowed the action I then had full access to my host PC from the client. This is obviously a major security problem for me. I'm sure I have made a mistake in the setup to allow this, but cannot see where, so any help greatly appreciated.

Thanks in advance.
