Routing: Site A via VPN through Site B to Site C

  • Hi there,
    I've got the following situation:
    Site A (bintec Router - has a VPN-Connection to Site B (bintec Router too -
    Site B has also a VPN-Connection to Site C (pfSense 2.3.2-RELEASE-p1 -

    I would like to access Site C from Site A.
    The configuration (routing) in the router on Site A/B is correct.
    bintec told me, that I've to configure route backwards on Site C.

    Could someone help me, how to do it?
    I found a lot of How-Tos regarding this topic, but they all created new interfaces, where I don't know a possiblity how to do it with the actual firmware.

    Thanks a lot and kind regards,

  • on site-A you need a route for with gateway:site_b_tunnel_address_X
    on site-C you need a route for with gateway: site_b_tunnel_address_Y

  • Hi!

    Site A is configured correctly.

    My problem is, that I dont know how to configure the specific routing in the pfSense. Could someone tell me how to do this?

    Thanks a lot.

  • This depends on your VPN setup. If you're running a site to site server or the client on site C add to "IPv4 Remote networks".

  • Hi Viragomann,

    it's a site to site connection.

    But I don't know how respectivly where to add the configuration.
    In VPN=>Tunnel=>Phase2 I can change the remote network, but not add an additional.
    Under System=>Routing => Static Routes, I could add a route, but can only select LAN or WAN as gateway, not VPN.

    Excuse my dumb questions, but it's my first time with pfSense.

    Thanks a lot.

  • So it's an IPSec VPN. You should have mentioned this.
    I'm not familiar with IPSec on pfSense, but there is a special topic in this forum:
