How to setup OpenVPN Server inside VirtualboxVM running Debian on Debian Host?
At Guest System OpenVPN is running to tunnel all internet Traffic to another VPN-Server.



Now I want to setup an OpenVPN Server on that Guest System to get access on NFS running there. (NFS over VPN)



PS: Which Cipher to prefer to get best performance on Raspberry Pi VPN Client?



--
Initial OpenVPN Server Setup is up, and I can connect to VPN but no Traffic forwarded and no ICMP Pings.
Ipv4 Forward in sysctl is enabled.
