Firewall filters in MikroTik RouterOS control packet flow by allowing or blocking traffic through predefined chains (input, forward, output) with options to accept specific services or drop malicious packets. Configuration is done via `/ip/firewall/filter` for IPv4 and `/ipv6/firewall/filter` for IPv6, with examples provided for securing both router and LAN devices.

Packet Sniffer is a MikroTik RouterOS tool for capturing and analyzing network packets to diagnose issues or detect security threats. It supports filtering by IP, MAC, port, protocol, and more, with options to save packets in PCAPNG format or stream them to a PC for analysis.
