        Ending note:

        In order to finalize the site-to-site setup on our end, please provide these values via Site-to-site request from in the NordLayer Control Panel:

        • Pre-shared key - you can generate it or we can provide it
        • Encryption  details (AES, SHA and DH group) - AES256, SHA256 and DH group 14 are recommended (also must support IKEv2)
        • Remote gateway/router public IP (must be reachable while connected to the dedicated server)
        • Remote subnet and mask (the subnet is used in your local network)

        Note: In case you are experiencing different results, make sure that you have you carefully gone through all the steps. Having said that, in case the issue persists please feel free to contact our 24/7 customer support team.
