Mikrotik Router: Troubleshooting OpenVPN Server Connection with Two WAN Providers
Mikrotik routers are popular choices for small to medium-sized businesses and organizations due to their versatility and affordability. One common use case for Mikrotik routers is setting up a VPN server to securely connect to the internet through multiple WAN providers. However, configuring an OpenVPN server with two WAN providers can be challenging, and troubleshooting connection issues can be time-consuming. In this article, we will discuss the key concepts and provide steps to troubleshoot OpenVPN server connection issues with two WAN providers on a Mikrotik router.
Mikrotik Router Standard Settings
Assuming that the Mikrotik router is connected to the first WAN provider, and everything is working fine. When trying to connect to the second WAN provider, the OpenVPN server on the Mikrotik router stops.
Checking OpenVPN Server Status
The first step in troubleshooting OpenVPN server connection issues is to check the OpenVPN server status. You can do this by logging into the Mikrotik router's web interface and navigating to the /system script menu. Here, you will find the OpenVPN server script. By clicking on the "Run" button next to the script, you can check the OpenVPN server logs for any errors or warnings.
Checking WAN Interfaces
If the OpenVPN server logs do not provide any useful information, the next step is to check the status of the WAN interfaces. You can do this by navigating to the /interface menu and selecting the WAN interfaces. Make sure that both WAN interfaces have a valid IP address and are up.
Configuring OpenVPN Server for Two WAN Providers
If the WAN interfaces are up and the OpenVPN server is not starting, it is possible that the Mikrotik router is not configured correctly for two WAN providers. To configure the OpenVPN server for two WAN providers, follow these steps:
- Create two OpenVPN server profiles, one for each WAN interface.
- Configure each OpenVPN server profile with the appropriate IP address, subnet, and port.
- Configure each OpenVPN server profile with the correct firewall rules to allow incoming VPN connections.
- Configure each OpenVPN server profile with the correct encryption settings.
- Configure the Mikrotik router to use the appropriate OpenVPN server profile based on the WAN interface.
Troubleshooting OpenVPN Server Connection Issues
If the OpenVPN server is still not starting, there are a few things you can try:
- Check the Mikrotik router's logs for any errors or warnings.
- Make sure that the OpenVPN client software is correctly configured.
- Check the firewall rules on both the Mikrotik router and the OpenVPN client to ensure that they allow incoming and outgoing traffic on the OpenVPN port.
- Try disabling the other WAN interface to see if the OpenVPN server starts.
In summary, troubleshooting OpenVPN server connection issues with two WAN providers on a Mikrotik router can be challenging, but by following the steps outlined in this article, you can identify and resolve common issues. Remember to check the OpenVPN server logs, ensure that both WAN interfaces have valid IP addresses, and configure the OpenVPN server correctly for two WAN providers.
