Rene,
I’m using Android 4.4.2 on a Google Nexus 10. I’ve reinstalled 'OpenVPN for Android". It immediately asked me to add a Profile. I did this & it showed me a screen containing hotspots for Basic, IP and DNS, Routing, Authentication/Encryption, Advanced, Generated Config. I’ve set Type in Basic to Username/Password. I’ve set the server address in Basic to the Internet IP Address set in my router. I’ve set the CA Certificate to the ca.crt created file. I’ve left the Client Certificate as ‘No Certificate’. I’ve set username in Basic & left Password blank. Ideally, I want to just use the VPN for internet banking. What’s the best way to do that i.e. to not use the VPN for mail or iother internet browsing?
