I'm trying to create a VPN server on Android. It can be any protocol, including PPTP, L2TP/IPSEC/OpenVPN, etc.
I tried it with Termux + AnLinux + CentOS, but I can't get it to work.
Is there any way, via an app or something else, to setup a VPN server on Android?
To be clear: I want to setup my Android phone as a server, not as a client.
