#106 flag to enable openvpn-dco, switch cipher from AES-128-CBC to CHACHA20-POLY1305

sgk requested to merge feat/openvpn-dco into main
  • adds a flag to optionally enable openvpn-dco on selected gateway hosts
  • switch from AES-128-CBC to CHACHA20-POLY1305 since AES-128-CBC is not supported by openvpn-dco

Ref: https://community.openvpn.net/openvpn/wiki/DataChannelOffload

When starting openvpn it will automatically detect DCO support and use the kernel module. Add the option --disable-dco to disable data channel offload support. https://github.com/OpenVPN/openvpn/blob/master/README.dco.md#getting-started-linux


For this to work, we have to upgrade the openvpn container image to install openvpn >=2.6
