In RouterOS, what does mangle mean?

In RouterOS, "mangle" refers specifically to the functionality that allows for the modification of packets as they traverse the router. This can include changing various attributes of packets, such as adjusting the IP header information, altering the internal routing table, or marking packets for different purposes, such as Quality of Service (QoS) or traffic management. The mangle table is a crucial part of packet processing in RouterOS because it facilitates advanced networking operations by enabling customized handling of packets based on various criteria.

This capability is essential in complex network setups where handling traffic efficiently or routing packets accurately is paramount. The mangle functionality can be particularly useful for prioritizing certain types of traffic, managing bandwidth, or even redirecting packets, thereby enhancing overall network performance and reliability.
