I'm having a weird issue. When I try to login to my Teamviewer from my mother's house, I cannot login to my Teamviewer account. Teamviewer thinks there is some kind of proxy server that is getting in the way, but I don't know what proxy server they are looking for. So what I've done is used a VPN service, and when I use that service, Teamviewer has no problem logging in, and I can access my remote computers. If you need additional information about the ISP, I suppose I can provide it.
