NetFilter SDK for MacOS, PF version
====================================

NetFilter SDK for Mac OS, PF version is a framework for transparent filtering of data packets transmitted over a network. It is suitable for developing content filters, basic application-level firewalls, traffic analyzers/shapers, and other software that requires viewing and modifying TCP traffic and controlling access to UDP.

Key features
-------------------------
- The solution allows filtering of outgoing TCP connections in both directions and blocking of UDP datagrams in a user-mode application. It is possible to filter a specified subset of connections/datagrams, restricted by filtering rules. Outgoing TCP connections can be redirected to a different address.
- Both IPv6 and IPv4 are supported.
- The process and user context is available for all network activity.
- Filtering works on Intel and ARM64 platforms.
