Client Application in CodeTwo Email Signatures for Email Clients cannot connect to the Administration Panel using a VPN connection.


CodeTwo Email Signatures for Email Clients is designed to connect only through Local Area Network (LAN), VPN connections were not taken under consideration when developing current versions of the software. However, there is still a way to connect Client Application to the server through Virtual Private Network (VPN) connection.

Please be advised that this way of connection is not officially supported, so the below described solution should be considered a workaround.
