NetPro

A Lineage 2 network packet analyzer with a JavaFX interface. It works as a proxy: it captures and decodes client-server traffic in real time and opens offline packet logs. This build goes well beyond the original: it supports official clients from many regions, modern protections and can export game data.

Key features

• Official clients from many regionsKR, TW, EU, RU, NA and more. The built-in sniffer captures traffic from High Five and 563 clients directly.
• Frost and ActiveAnticheatSupported through DLL injection: capture works where an ordinary proxy cannot.
• System capture without a DLLSystem capture and autoproxy detect server addresses automatically. For clients with Frost or ActiveAnticheat use DLL injection.
• Game data exportExport spawns, multisells and other categories to TXT/XML: named records are saved in one category file straight to the folder you choose.
• Spawn workspaceCombines collection from packet logs with live collection. Outline an area on the map to export and save areas for reuse.
• Works with AI assistantsClaude, Codex, Cursor and other assistants work with the program through MCP.
• New clientsPacket definitions and opcodes for localized 591 (Forged in Battle) and Korean 591KR (Iron Masters), Fafurion 196 support in the DLL, and separate multisell name maps for Main, Classic and Essence.
