What Port 3200 Is
Port 3200 sits in the registered ports range (1024–49151). IANA officially lists it as "Press-sense Tick Port" — an assignment so obscure that almost no documentation about it exists in the wild.
What the port is actually used for, on servers worldwide, is something else entirely: the SAP Dispatcher.
The SAP Dispatcher
SAP's enterprise software stack — R/3, NetWeaver, S/4HANA — uses a process called the Dispatcher to receive incoming client requests and route them to available work processes. When an SAP GUI client connects to an application server running as instance 00, it connects on port 3200.
The pattern is deliberate: SAP Dispatcher ports follow the scheme 32NN, where NN is the zero-padded instance number:
| Instance | Dispatcher Port |
|---|---|
| 00 | 3200 |
| 01 | 3201 |
| 02 | 3202 |
| ... | ... |
| 99 | 3299 |
This lets a single physical server run multiple SAP instances simultaneously, each on its own port in the 3200–3299 range, without collision.1
SAP GUI for Windows and SAP GUI for Java both use this port. When a user opens their SAP logon pad and double-clicks a system entry, the first connection goes to the Dispatcher on port 32NN. The Dispatcher then hands the session off to a work process.
Security Considerations
Port 3200 appears frequently in SAP-targeted security assessments. Exposing the SAP Dispatcher directly to the Internet — rather than routing through SAProuter or a VPN — is considered dangerous. The Dispatcher is an internal routing mechanism, not designed for public-facing exposure.
Security tools like Metasploit have modules specifically for probing SAP services on the 32XX port range.2 If you see 3200 open on a network scan of a server you don't recognize, there's a reasonable chance it's an SAP system.

The process name in the output will tell you immediately whether this is an SAP work process, a development tool, or something else entirely.
Why Unassigned Ports Matter
Port 3200 illustrates a recurring reality in the port system: the official IANA registry and actual usage diverge constantly. IANA can assign a port to Press-sense Tick, but it cannot compel SAP — one of the world's largest enterprise software vendors — to use a different port. De facto standards emerge through deployment, not registration.
The registered port range (1024–49151) is large enough that many ports have no meaningful official assignment, while simultaneously being in heavy unofficial use. Understanding a port means knowing both the registry entry and what actually runs on it in practice.
