OpenVPN Site-to-Site through Roadrunner



  • Hi All,

    I was  wondering if anyone has managed to setup something similar to this:

    Client A (OpenVPN Roadrunner) -> Site A (10.0.0.0/16) -> Site to Site OpenVPN -> Site B (192.168.0.0/16).

    Basically I am trying to setup an OpenVPN client PC to connect to pfsense at Site A, then to use the Site to Site VPN between Site A and Site B to connect to Site B on a different network.

    Do you think this is possible?

    Thanks in advance.



  • Yes, this is pretty common.  Just need to configure separate instances of openvpn (one for the site-to-site and one for roadrunner).

    On the road warrior config, you just need to push a route to Site B's LAN.



  • Let's assume the SiteA RoadRunner tunnel is 10.42.42.0/24
    On SiteB site-to-site Remote Networks put 10.0.0.0/16,10.42.42.0/24
    On Site A RoadRunner server Local Network/s put 10.0.0.0/16,192.168.0.0/16
    Then routing will work.

    Make sure rules on OpenVPN at SiteA and SiteB allow the traffic to/from those subnets.
    Then firewalling will allow the traffic.

    I connect in like this all the time, to 1 office, and use the whole internal network across lots of offices.
