Site to site vpn with wireguard, or...

<< < (2/2)

gbr:
So, this is kind of working.

From the OPNSense firewall I can ping any machine on the other side of the VPN. From a machine behind the OPNSense firewall, I can't.


remote network 172.31.0.0/16 <---> Ubuntu Wireguard Server <----> OPNSense Wireguard client <---> local network 192.168.100.0/22

The local network can't ping the Ubuntu Wireguard server or the remote network, only OPNSense can.

I'm missing something easy, I think.

gbr:
Never mind, it was easy. I forgot the localnetwork in AllowedIPs on the server.

Currently, they run a Wiregaurd server (not OPNSense). Their internal network is 172.30.0.0/16.

I run OPNSense as my firewall, and would like to create a link to their servers so anyone in our office can access the servers in their office. My internal network is 192.168.200.0/22

What's the best way to set this up? Will OPNSense and wireguard do it for me or should I create a separate machine behind my firewall to create the link and route through that?

Are there any HOWTO's to set this up?
