List of protocols

Built-in protocols — updated along with the SSG software version. Installing a new version requires a DPI reboot, which causes traffic interruption.
If needed, they can be supplemented with up-to-date attributes from the VAS Cloud. This is only necessary for complex protocols, but the option is available for all.
Cloud protocols created by VAS Experts — are periodically updated from the VAS Cloud. This ensures that popular applications remain up-to-date as their behavior changes. Description
Custom (user-defined) protocols — protocols created by users via the GUI using VAS Cloud tools. These have higher priority than those loaded from the VAS Cloud, and within them, IP:PORT takes precedence over IP and CIDR. It is possible to add a protocol based on IP, SNI, or AS. Guide.
DSL protocols — protocols described in the DSL language and connected to DPI as a separate module, without reinstalling the software or causing traffic interruption. Unlike custom protocols, a DSL protocol is a finite state machine that analyzes the first N packets of a flow against defined conditions (ports, AS numbers, payload bytes, DSL expressions) and determines whether the flow matches the protocol.
DSL protocols are created by VAS Experts specialists upon client request to Technical Support.
