Firewall Ports

StifleR Ports

The following (client) ports are used for the InterVLAN feature (see later). An asterisk (*) indicates a dynamic Port number. BranchCache tries to use a random port among the dynamic port range (49152-65535) as specified in RFC6335 section 6.

The table below describes the specific ports and communication flow used by the StifleR Client and BranchCache.
