Hello,
Thank you for contacting Teltonika Crowd Support.
RUT955 has got several VPN services, to set up to connect multiple RUT955s and allow remote clients to access any device on any of the RUT955s we have the ZeroTier VPN and also The VPN hub on our Teltonika RMS.
To set up Zerotier, first add ZeroTier to RUT955 if it is not yet added.
To do so go to Services >> Package Manager Search ZeroTier and on action add it to RUT 955.
Enable Zerotier and proceed to create an account at www.zerotier.com
At www.zerotier.com set up your network and link your RUT 955s to ZeroTier. From this you will be able to access all your RUT955s.
For more gudaince on how to set up ZeroTier kindly follow the following links https://wiki.teltonika-networks.com/view/ZeroTier_One_VPN_configuration
