OpenVPN Site-to-Site through Roadrunner

[ehuk]

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.
