      Hello!
      I'm implementing multiple Site2Site VPN with failover on multiple WANs.

      On the Server I configured one openvpn server per client, each with its own udp port. Every server is listening from localhost.

      Every WAN connection has a CARP IP NATed to localhost for the OpenVPN udp ports.

      When a client connects to the VPN, it is unable to bring the tunnel up, because of this message on server log:

      "TCP/UDP: No outgoing address to send packet "

      Putting in the custom options:

      local x.x.x.x (CARP VIP of WAN)

      the tunnel goes up.

      Any help appreciated, I'm out of ideas!

      EDIT: I forgot to mention that if I connect to WAN IP (No matter which) the tunnel goes up.

        SOLVED!
        I reviewed my settings: I made NAT rules for WAN Address instead of CARP VIP.
        Changed NAT Rules to CARP VIP (openVPN Port) -> localhost.
        Now it works like a charm and failover is great!
