OpenVPN Clients – Routing Traffic to OPT1

pfsense

I'm trying to route traffic from OpenVPN clients to a host connected to my pfSense's OPT1.

  • OpenVPN network: 192.168.9.0/24
  • OPT1 network: 10.139.251.104/29
  • OPT1 address: 10.139.251.109
  • Destination host I am trying to connect to: 10.195.111.12/26

pfSense itself has no problem communicating with 10.195.111.12/26, but I am at a loss how to route traffic from OpenVPN to it. I thought it would be as easy as adding a route 10.195.111.0 255.255.255.192 line to my .ovpn configuration file, but apparently not.

I'm sorry if this sounds trivial but I'm not a network engineer, just trying to connect to a server so I can use the database on it. Any help would be appreciated 🙂

In addition to the OpenVPN clients that need to have a route to send the packets into the tunnel, the gateway needs to have a route to the destination when that isn't the (likely configured) default route.

Also, the other gateways (pfSense, ...) require a route back to the OpenVPN clients unless they can use their default gateway.
