TeamViewer connection issues on CentOS 7 VM

I have a virtual machine with CentOS 7 at school, but I need to work from home. So, I followed a tutorial to install Gnome and another to create a VNC server, all this to install TeamViewer. Then, I install TeamViewer 11, but when I open it, it says the famous message: Not ready, Please check your connection I tried to input proxy settings, but it didn't save the changes, so I had to edit the global.conf file. I know that the proxy is well in the system because I can navigate; I can even ping 178.77.120.1, and it works. But the problem still remains. Then, searching the web, I saw I could change the SELinux config to permissive. I do that in another virtual machine, and that works, but it doesn't work on my machine. It has a Wine problem. I try to fix it using the following: # setsebool -P mmap_low_allowed 1 but that doesn't work. Another solution was to add to mdns4 to host in /etc/nsswitch.conf, but it doesn't work. So I decide to uninstall, using: rpm -qa | grep teamviewer rpm -e But when I installed TeamViewer again, it loaded the proxy settings, so I think it didn't completely remove them.
