OpenVPN Multi-Wan

Just wondering how I configure OpenVpn for the Client to hit the server side’s Muli-Wan. How do I configure the client side to go to more than one IP.

In the past I have used Quagga OSPF, but I see that is depreciated now in favor of FRrouting. Is this the correct direction to go? Is there a more simple solution that I am missing?

They have how to set that up documented in pfsense here

Thanks that helped. I got it to work but I guess the question is how to do I incorporate gateway group failover . This works but when I take down WAN its stays on WAN2 and doesn’t switch back to WAN when WAN comes back up. (WAN 200mb, WAN2 8mb) Currently its set up like this

I ended up port forwarding

Interface: WAN
DEST. ADRESS: Wan address
DEST. PORT: 1199
NAT IP 127.0.0.1
NAT PORT: 1199

and
Interface: WAN2
DEST. ADRESS: Wan2 address
DEST. PORT: 1199
NAT IP 127.0.0.1
NAT PORT: 1199

I switched the VPN interface to Localhost

On the remote side I added the WAN2 to the advanced remote xx.xx.xx.xx 1199;
