OpenVPN lan-to-lan communication with external clients

[Sota]

Hello everyone,

I have a Site A and Site B connected with a OpenVPN lan-to-lan. Site A OPNsense firewall is the server and site B OPNsense firewall is the client. The communication between these two sites is perfect. External clients connect to site A because it is there that most servers are. The communication between site A and external clients is perfect also. The external clients use OpenVPN. However external clients cannot reach site B where the file server is.
 
Is it possible to have external clients that connect to site A to communicate as well with site B?

I have an image with the configuration to help.



Thank you!

Yes, I did find a solution.

Modify site A road warrior server that serves the VPN clients to accept packets from 192.168.6.0/24, do that in IPv4 Remote Network field (172.16.2.0/24,192.168.6.0/24). Then in Site B firewall update as well the road warrior client IPv4 Remote Network field (172.16.2.0/24,10.37.85.0/24).

Hope that helps.
