Dual WAN with OpenVpn



  • Hello Rescuers,

    I try to create a setup with the following goals in mind:

    • Site to Site VPN using OpenVPN
    • Dual WAN connections on the primary site
    • Single WAN conection on the secondary site
    • VPN fully redundant, if ISP 1 or 2 goes down, the tunnel stays up.
    • Pfsense 2.0
    • ISP (1,2,3 ) dynamic ( with DYNDNS )
      I came with the following design so far:

    LAN-1
      |
      |
      |   
    pfSense1 (OpenVPN Primary side)
    |  |
    |  |
    |  |       
    ISP1 ISP2 two openvpn link
    |  | 
    |  |
    (Internet)
      |
      ISP2 -accidentally
      | 
    pfSense2 (OpenVPN Server side)
      |
      |
      |
      LAN-2

    Has anyone done this successfully and instructions?
    Thanks



  • You have a few options.
    I think the easiest one would be to set up two servers on pfsense1 (one per isp, both with the same port, psk, compression…).
    Setup one client on pfsense2.
    You can have the client try to connect to a dyndns address that is assigned to the active wan connection on pfsense1.
