PiVPN - Site-to-Site VPN

Post by ebnerjoh » Wed Dec 16, 2020 7:19 am

Hi,

I have two networks.

Network A: 192.168.1.0/24
Network B: 192.168.0.0/24

In both networks I have a Raspberry Pi with a PiVPN Installation.

I can connect with "Client-to-Server" to both OpenVPNs and accessing the ressources in each Network.

I want now to setup a Site-2-Site VPN so that I can connect from Network A to Network B (other side around should be denied).

Unfortunatley I was not able to figure our how the config needs to look like, especially with PiVPN.

Br,
Johannes

You have it working, then it is a matter of firewall configuration which basically is off topic.
This should help getting started:

Hi,

I think there is a missunderstanding.

I have on both OpenVPN a Client-to-Server Config running. thats working (created with the PiVPN add user script)

But I want to connect both OpenVPN instances so that all clients in LAN A can connect to LAN B

openVPN Site-2-Site Network

Post by ebnerjoh » Fri Dec 18, 2020 6:38 pm

Hi,

I have two seperate Networks:

Network A: 192.168.1.0/24
Network B: 192.168.0.0/24

I want that all clients from network A are reaching Network B

I installed in each network a raspberry Pi with PiVPN (OpenVPN).

Then I have setup a Config on the PiVPN in Network B and imported it on the PiVPN on Network A. Network A PiVPN was successfully connected to PiVPN on Network B.

After I added the following route I was able to ping all clients on Network B from the Raspberry on Network A:

Code: Select all

sudo ip route add 192.168.0.0/24 via 10.8.0.4 dev tun1
Then I thought I am nearly finished and just have to add the default route on the router on network A to point 192.168.0.0/24 to the PiVPN in Network A but unfortunatley not. I cannot reach Network B from any client on Network A, except the PiVPN itself.

What do I miss?

A tracert from a Client on Network A to a Client on Network B shows me that the default route is working, but it got stuck on the PiVPN
