MikroTik as OpenVPN Client on Opnsense - no Traffic possible

Hi there,

im just trying to get a a VPN between a MikroTik LTE Device (wapLTE) and a Opnsense Firewall to working.
I set up a OpenVPN Server on the Opnsense Site and added a OpenVPN Client Interface to the MikroTik.
I have already a connection between the Mikrotik and the other side. On the Terminal from the MikroTik i can ping into the remote Subnet. But the connected Clients on the MikroTik cant reach the remote Subnet.

What i’m missing?

Hi,
i had similar issue.
My scenario:
Main site: 2x OPNsense in HA (25.1.11), LAN: 192.168.1.0/24
Remote site: MK hAP ac2 (7.19.3), LAN: 192.168.2.0/24

Interconnected via OpenVPN (172.16.0.0/24). Once tunnel established it creates new interface under “Interfaces” → “Assignments”. I called mine as “OVPN-Remote”. Physical iface name is something as “ovpns1”. Unless you assign it and enable it, you’re not be able to create Gateway and Route.

Than go to “System” → “Gateways” → “Configuration” and add new gateway.
Name: Remote-mk (or whatever you want)
Interface: OVPN-Remote
IP: 172.16.0.1 (as tunnel always would have .1 from the tunnel subnet)

When created go to “System” → “Routes” → “Configuration” and add new route.
Network address: 192.168.2.0/24
Gateway: Remote-mk - 172.16.0.1 (or name of your GW)

That made my routing work. Also check if you’re pushing the right routes via OpenVPN settings in the “Remote Network” and “Local Network”. And also check if you have allowed traffic under the “Firewall” → “Rules” → OVPN-Remote (or name of your interface).

Hope that helps.
