Contemporary Controls offers three VPN solutions to meet your remote access needs—our RemoteVPN subscription service, and our Self-HostedVPN and BridgeVPN solutions.
BridgeVPN allows users to set up and maintain their own single-site, secure remote access without subscription fees and without the need for a cloud-based VPN server. Our EIGR-VB Gigabit IP router can be configured to operate in OpenVPN server mode as a wired bridge VPN server. The EIGR-VB router can support up to 10 VPN clients on Windows and Linux PC. These clients can be located anywhere that has Internet connectivity.
The VPN clients are bridged to the router's LAN side and assigned an IP address from the LAN subnet. This provides the same application experience as if the client devices were part of the EIGR-VB's LAN and allows passage of multicast and broadcast messages through the VPN tunnel. This facilitates easy and secure remote access to BACnet devices at remote sites without the need for a BACnet/IP Broadcast Management Device (BBMD).
Any Windows or Linux PC can run the open-source OpenVPN client software. Though OpenVPN client software is available from the Google Store for Android devices and App Store for iOS devices, it doesn't support TAP adapter required for bridge mode. For PCs, OpenVPN Version 2.x is required which corresponds to OpenVPN GUI on Windows. OpenVPN Connect (version 3.x) is not supported with BridgeVPN as it doesn't support the TAP adapter.
New support documentation provides an overview of our BridgeVPN solution and BridgeVPN EIGR-VB router, applications for BACnet networks, and instructions on how to configure the EIGR-VB as an OpenVPN server.
