Important information | This node is available only for specific protocols. For a complete list of protocols and their associated nodes, see the Protocol compatibility table.

User interface elements are described below (unlabeled elements are shown in angle brackets):

UI Element | Description
--- | ---
Capture level | For port mapping only: The level of data to capture (relevant only for HTTP based protocols): Socket level data. Capture data using trapping on the socket level only. Port mappings apply in this case (default). WinINet level data. Capture data using hooks on the WinINet.dll API used by certain HTTP applications. The most common application that uses these hooks is Internet Explorer. Port mappings are not relevant for this level. Socket level and WinINet level data. Captures data using both mechanisms. WinINet level sends information for applications that use WinINet.dll. Socket level sends data only if it determines that it did not originate from WinINet.dll. Port mapping applies to data that did not originate from WinINet.dll.
Network-level server address mappings for | For port mapping only: Specifies the mappings per protocol. For example, to show only the FTP mappings, select FTP.
<Port mapping list> | A list of the port mappings. You can temporarily disable the settings for an entry by clearing the check box adjacent to it. When the check box is cleared, VuGen ignores the custom settings for the entry and uses the default settings—it does not cause the host:port to be ignored. To filter a host and port, use Traffic Filtering.
<Traffic filtering list> | A list of the traffic filters, indicating the server name, port and filtering level. Click New Entry or Edit Entry to set these values. Clear the check box adjacent to an entry to disable it temporarily. When you launch VuGen, all unchecked port mapping entries are converted into traffic filter entities.
New Entry | In the Port mapping section: Opens the Server Entry dialog box, allowing you to add a new mapping. For user interface details, see Server Entry - Port Mapping dialog box. In the Traffic filtering section: Opens the New Entry dialog box, allowing you to add a new traffic filter. For user interface details, see Server Entry - Traffic Filtering dialog box.
Edit Entry | Opens the Server Entry or New Entry dialog box, allowing you to edit the selected entry.
Options… | For port mapping, this button opens the Advanced Settings dialog box to enable auto-detection of the communication protocol and SSL level. For details, see Advanced Port Mapping Settings dialog box.
