At a 'WMS-UTR' project deployment, Huawei DPI equipment operating alongside Geedge TSG at sites abbreviated TWA/PCAP/MSH independently applies a SIP-protocol Deny policy with IP allowlisting -- confirming TSG is deployed in a multi-vendor stack alongside Huawei DPI hardware at the same customer site, not as the sole detection layer.

An 'ADC Hardware Installation and Configuration Guide' (v21.11) describes a modular chassis (Switch Sled, CPU Sled) matching taxonomy's Pakistan/WMS-UTR 'ADC hardware' reference, confirming ADC is a distinct deployed hardware line -- not just a site nickname -- with its own installation documentation separate from the TSG-X/TSG-7400 line.

A thesis-project assignment for hidden-service (VPN/Proxy/Tor) identification via heterogeneous graph neural networks on flow logs sources its one day of training data from a database explicitly named 'tsg_galaxy_p19' — tying the internal TSG naming convention to the taxonomy's P19/WMS-UTR Pakistan site codename — accessed over an internal 'Information Harbor' (信息港) VPN, with ground-truth hidden-service IP labels supplied by the commercial IP-intelligence service spur.us.

At a Pakistan site (P19/MSH), Geedge identified that TCP RST-injection for a Deny action fails on asymmetric ('unidirectional') flows because the synthetic RST packet lacks GRE callid/routing context only present when both directions transit the same node. Two fixes are in progress: a dedicated third-layer packet-injection route, or a cluster-wide coordination mechanism ('SwarmKV') that syncs which policy a session matched across nodes so each node can independently inject its own side's interference packet.

TSG/CM ships with pre-built, first-class 'Learning Object' entries specifically for Freegate (Object ID 18) and Psiphon3 (Object ID 19), plus a generic 'Top Server IP' object (ID 20) -- default product features, not customer-commissioned custom signatures. The Psiphon3 object auto-learns and dynamically updates a live blocklist that reached roughly 70,000 IPs at one deployment before a database issue temporarily dropped it to ~50,000.

Ethiopia (E21) customer specifically tested Melon VPN and Ultrasurf against TSG; Ultrasurf's frequently-rotating IPs required an updated signature (successfully blocked after update), while Melon VPN's connection succeeded but was non-functional for other reasons (not attributed to TSG blocking).

A companion recurring report family, "Tiangou Secure Gateway — Server IP and Location of Overseas APP", automatically compiles TOP10/TOP50 server-IP-and-geolocation tables per major Western platform (BBC, Discord, Facebook, Gmail, Google, Hulu, ESPN, Messenger, etc.), i.e. an automated pipeline for building IP-block target lists against specific foreign services from observed traffic, generated on a similar recurring cadence.
