Dual Wan and Openvpn - node to node?

  • I 'm upgrading a branch site to a dual adsl (two isps) WAN.  Current vpn via openvpn to a data center.

    Which is the best option with pfsense at the branch end?

    * Load balance over WAN links - one openvpn tunnel
      * Two openvpn tunnels and load balance vpn traffic over these tunnels
      * Something else
