RouterOS NAT packet handling

Sat Oct 03, 2020 12:42 am

Hello,
When RouterOS performs NAT/PAT on a packet, does it re-write the entire packet or just change the necessary header info and re-checksum what changed?
Specifically I am concerned with dstnat.
I've read through several documents about NAT but the do not describe it in enough detail.

TIA
