How does Eddie build OpenVPN directives?

The Settings -> OVPN directives page controls how OpenVPN directives are built in the final configuration file.
Directives are defined in the following order:
  • Base directives
    Changing or removing these directives may cause client to not work properly.
    Current default: 
    client
dev tun
resolv-retry infinite
nobind
persist-key
persist-tun
verb-3
connect-retry-max 1
ping 10
ping-exit 32
explicit-exit-notify 5
  • Provider directives (specific for each provider, for example cipher)
  • Server directives (specific for each server)
  • Computed directives based on other settings (for example protocols, proxy, routes etc)
  • Custom directives

If you choose Use only custom directives, only Computed directives and Custom directives are applied. This setting is generally used for debugging/testing.
If the same directive exists in different areas, and is a directive that can be specified only one time, the latest is used. The following directives can be specified multiple times: 

remote
route
plugin
x509-track
http-proxy-option
ignore-unknown-option
