Blitz is a firewall that works by ARP spoofing/NPD spoofing devices in your network to allow for packet inspection and filtering learning project for me to become more familiar with Rust. It is written in Rust using tokio, libpnet and others.

This is in the proof of concept stage/hobby. DO NOT use it for production applications.

• Send ARP spoofing to target devices pretending to be the router
• Send ARP spoofing to router pretending to be the target devices
• Can perform ARP queries
• Send NDP spoofing to target devices pretending to be the router
• Send NDP spoofing to router pretending to be the target devices

• Implements DHCP server for IPv4
• Forwards packets upstream

• Does reverse DNS of packet's source/destination to find traffic flows
• Can log tx/rx to a specific host
• Can filter packets based on IP ranges
• Can filter packets based on specific hostnames
• Can filter packets based on RegEx on hostnames
• Can create log files of traffic data
