The /etc/init.d/vpn-service script has the function openvpn_server for starting a OpenVpn server:

openvpn_server() {
local enable=uci get vpn_service.global.enable
local vpn_port=$(uci get vpn_service.vpn.port)

if [ “$vpn_port” = “80” -o “$vpn_port” = “83” -o “$vpn_port” = “443” ];then
logger -st $NAME “port is occupied, please use another port.”
return 0
fi

if [ “$enable” != “1” ];then
return 0
fi

local cfg=uci get vpn_service.global.ovpn
if [ ! -e “$cfg” ];then
logger -st $NAME -p3 “Openvpn server config no found.”
return 0
fi

start_server “$cfg”
}
