You spin up the container, generate client certificates with EasyRSA, then run ovpn_getclient <client_name> to get a ready‑to‑use config. Perfect for batch‑creating configurations for multiple clients.
Here is the general workflow for using a generator to secure your MikroTik router: Step 1: Generate Configuration Commands Access your chosen Mikrotik OpenVPN config generator.
./mikrotik-ovpn-gen \ --mode ip \ --public-ip vpn.example.com \ --port 1194 \ --proto udp \ --client-subnet 10.10.20.0/24 \ --route-lan 192.168.88.0/24 \ --user roadwarrior \ --dns 1.1.1.1 \ --out mikrotik-script.rsc \ --client-config client.ovpn
: A YAML-based tool that automates the generation of certificates (CA, server, and client) and configuration files. Key Features Static IP Management
: If you can connect but cannot access internal assets, verify that Proxy ARP is enabled on your local bridge interface ( /interface bridge set [find] arp=proxy-arp ). To help refine your networking setup, please share: Your RouterOS version (v6 or v7)? The client operating system (Windows, Linux, mobile)? Do you need site-to-site or road-warrior access? mikrotik openvpn config generator
One of the most detailed and modern blog posts on this topic is by Martin Konicek
/ip firewall filter add chain=input protocol=tcp dst-port=443 action=accept
Use firewall rules to limit what VPN clients can reach. For example, allow only specific IP ranges or ports. The only-one=yes option in the PPP profile prevents multiple sessions from the same username.
OpenVPN over UDP is faster (no triple handshake), but some restrictive firewalls only allow TCP port 443. The generator must support both. You spin up the container, generate client certificates
configuration files required by most clients. To bridge this gap, several automated tools and guides have been developed to generate these configurations. Top Resource: Martin Konicek's OpenVPN Config Generator
And somewhere, on a server that never slept, the MikroTik OpenVPN Config Generator logged one more silent, successful generation.
RouterOS v7 fully supports UDP, which offers significantly better speeds than TCP.
| Problem solved | How this feature fixes it | |----------------|---------------------------| | Forgetting to add firewall rules | Auto-adds input + forward rules | | Wrong cert paths in OpenVPN | Embeds cert inline | | Client can't reach LAN | Adds iroute + route in profile | | UDP fragmentation issues | Recommends mss clamping | | No logging / debugging | Adds /log message when tunnel starts | The client operating system (Windows, Linux, mobile)
This Docker image bundles OpenVPN with EasyRSA and is specifically set up for MikroTik routers. It comes with a handy script called ovpn_getclient , which dumps a complete inline OpenVPN client configuration file—meaning all certificates and keys are embedded directly into the .ovpn file, no separate file management needed.
Fully compatible with OpenVPN (Windows, Linux, macOS, iOS, Android).
Set days-valid to a reasonable period (e.g., 365 days for clients, 1825 days for server and CA) and have a renewal process in place.
