Connection between two OpenVPN Server (site-to-site –- remote)



  • Hi,

    on my first pfSense firewall (PFS 1) I've installed two OpenVPN server - one as site-to-site to another pfSense firewall (PFS 2) and one as a remote for accessing it with my smartphone and other clients.
    Everything is working fine but I cannot access PFS 2 when I connect to PFS 1 via remote access (smartphone etc).

    Please, how can I solve this issue respectively can you give me a hint in which direction I should search?



  • Really nobody?  :-
    Only a hint would be great



  • You've to set the OpenVPN routs for that.

    On PFS2 OpenVPN client add the access server tunnel network to the "Remote networks". On PFS1 in the site-to-site settings add it to the "Local networks".
    In the access server settings add the network behind PFS2 to the "Local networks."

    Check if your firewall rules allow the access.



  • Thank you very very much - it's working like a charm!
    But I only need setting 1 and 3. "On PFS1 in the site-to-site settings add it to the "Local networks"" was not necessary. Apart from this I think it should be the "Remote network(s)" because there is no "Local networks()" in the site-to-site settings –> On PFS1 in the site-to-site settings add it to the "Remote networks"



  • So you have a pre-shared key site-to-site server, here is only the remote networks option available.
