DxConnect-IoT Admin Guide


DxConnect-IoT allows the user to create direct secure connections (tunnels) between a remote client and one or more servers running DxEnterprise or DxOdyssey without the need for a VPN, expensive hardware, or data passing through a vendor portal. DxConnect-IoT transfers encrypted packages across system-assigned UDP ports so there is no need to open a TCP or UDP port to the internet. With DxConnect-IoT, data transfers securely between custom-designed tunnels. DH2i’s DxConnect-IoT uses a highly available proprietary cloud Matchmaking Service to keep connections alive, but no payload data is passed through the matchmaker – all data is directly encrypted between servers.

In DxEnterprise or DxOdyssey create the tunnels and assign a client to the tunnel. Then export the client configuration to a *.dh2i file for use with DxConnect-IoT. For more information on creating tunnels in either DxEnterprise or DxConnect consult the appropriate admin guide.
