Port Configuration
Video management systems (VMS) will generate Internet traffic if a system is provided with Internet access. Because of this, some port management may be needed to allow access through network security for systems to communicate with each other, especially if a DW Spectrum System is comprised of merged servers between different locations.
DW Cloud™ is part of a Peer-to-Peer (P2P) network that allows DW Spectrum users to easily connect with individual servers and merged systems but there may be instances where an enterprise Firewall prevents communication.
When a user attempts to connect with a camera remotely, the connection will first be routed to the DW Cloud server, which will then direct the connection to the DW Spectrum Server using the already established socket that was previously initiated. Authentication and connection will then be established between the connecting DW Spectrum Client and DW Spectrum Server, providing access to the camera.
The presence of a firewall or SonicWall can interfere with this P2P communication. This is why some network configuration may be required when using an Internet connection from behind a security wall.
This article will outline the relative port information required to allow access between DW Cloud and DW Spectrum systems.

FQDN/Allowlisting – Firewall/SonicWall Pass List
To allow a remote connection through a firewall or SonicWall with DW Cloud or a DW Spectrum Client interaction, the routing and Internet security settings of your network may require you to use a specified address list.
When configuring a firewall or SonicWall, FQDN (Fully Qualified Domain Name) format should be used in order to successfully allowlist the specific services of DW Cloud and DW Spectrum, as some of the endpoints do not inherently resolve to static IP addresses.
**NOTE: Please note that it is important to add all the FQDNs that are listed below to your firewall pass list, not just the ones that are specific to your region. To learn more about how the DW Cloud connection service work, you may refer to the article DW Cloud Overview.
