OpenVPN and failover ips?

I run OpenVPN with --multihome option, how to setup it the way i connect to failover ip (OVH failover to be clear) and show exit ip as i connect to failover ip? i managed to only show original ip of server not the failover one.

    I think you'd need 1:1 NAT for this, You can use iptables for this.
    https://dd-wrt.com/wiki/index.php/One-to-one_NAT

    That guide should cover the rules that you'll need (It did for me)

    I think you'd need to do it on a per-client IP basis, as I'm not sure how you'd automatically modify the rules depending on the IP used to connect.

    iptables -t nat -I POSTROUTING -s [VPN CLIENT IP] -j SNAT --to-source [FAILOVER IP]

    Something like that

    Thx much !!!

    Needed to add :

    iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to-source [FAILOVER IP]

    and it works now:)
