WinDivert 1.1: Windows Packet Divert
Windows Packet Divert (WinDivert) is a user-mode packet capture-and-divert package for Windows Vista, Windows 2008, Windows 7, Windows 8 and Windows 10.
WinDivert allows user-mode applications to capture/modify/drop network packets sent to/from the Windows network stack. In summary, WinDivert can:
- capture network packets
- filter/drop network packets
- sniff network packets
- (re)inject network packets
- modify network packets
WinDivert can be used to implement user-mode packet filters, packet sniffers, firewalls, NAT, VPNs, tunneling applications, etc.
The main features of WinDivert include:
- packet interception, sniffing, or dropping modes
- supports loopback (localhost) traffic
- full IPv6 support
- network layer
- simple yet powerful API
- high-level filtering language
- filter priorities
- silent installation
- freely available under the terms of the GNU Lesser General Public License (LGPL)
