Config Generator - Mikrotik Openvpn

RouterOS is not a standard OpenVPN server. Its compatibility mode requires specific flags that generic GUI clients (like OpenVPN GUI or Tunnelblick) do not enable by default.

Common issues without a proper generator:

A dedicated generator ensures every emitted .ovpn file is 100% MikroTik compliant.

If you are building a generator (Python snippet below), follow this exact order of operations:

This long-form content provides:

Note: RouterOS implements OpenVPN with limitations compared to typical OpenVPN server distributions (e.g., no UDP mode until recent versions, limited TLS options, username/password + certificate auth support differences). Assume RouterOS v6.x or v7.x depending on features; adapt parameters accordingly.

/certificate add name=ca common-name=VPN-CA days=3650 key-size=2048 key-usage=key-cert-sign /certificate sign ca /certificate add name=server-cert common-name= wan_ip days=3650 key-size=2048 /certificate sign server-cert ca=ca

If you manage 50+ MikroTik routers, using a web form is too slow. You need an automated config generator.

You can write a Bash or Python script that: mikrotik openvpn config generator

Template Example (Jinja2):

/ip pool add name=vpn_pool_ customer_id  ranges= vpn_start - vpn_end 
/ppp secret add name= username  password= password  service=ovpn profile=vpn_ customer_id

This is the "generator" at scale. It ensures every router gets identical, auditable configs.

The generator operates in three phases:

  • RouterOS Script Synthesis:
  • Client Config Export:

    • Ready to paste into /system script or terminal. RouterOS is not a standard OpenVPN server

    Example snippet generated:

    /interface ovpn-server server
set auth=sha1 certificate=server-cert cipher=aes256cbc \
    default-profile=ovpn-profile enabled=yes port=1194 \
    protocol=udp require-client-certificate=no

    /ppp profile
add name="ovpn-profile" local-address=10.10.20.1
