Client - pfSense - pfSense



  • Hi Guys,

    i have a new challenge for pfSense and OpenVPN:

    We got 2 pfSense:

    • pfSense A

    • OpenVPN Server
          Tunnel Network: 172.16.0.0/24
          Local Network: 10.0.0.0/8

    • OpenVPN Client to pfSense B

    • pfSense B

    • OpenVPN Server
          Tunnel Network: 172.16.1.0/24
          Local Network: 10.1.0.0/16

    What i should be able to do:

    Connect via OpenVPN to pfSense A and be able to access both Networks (pfSense A & B).

    How would you takle this? Any Ideas?
    I tried already a few things, but think that was not right.

    thx for your help



  • You want to set up a site to site tunnel, but you have fix a couple things first:

    • The tunnel network has to be on the same subnet

    • Your LAN subnets overlap.  This needs to be fixed before moving forward



  • You are having a "road warrior" server at Site A to "dial-in", then a site-to-site link from an OpenVPN client at site A to an OpenVPN server at site B.
    The tunnel network for "road warrior" and "site-to-site" have to be different subnets - what is in the original post is fine. (I think marvosa has misread your post, as I did when I first looked at it quickly)
    The local network at site A and site B have to be different and not overlapping. e.g. 10.0.0.0/16 and 10.1.0.0/16
    Then it is all standard stuff, no real challenge for pfSense. Put the appropriate things in local and remote network fields of the VPN settings, allow stuff in firewall rules, go.

    All right, it mean that i`m on the right way to apply this. i will give it another try and may also check the firewall settings - the problem could be there..
    many Thanks!
