From 7fe568ca1672f1dfbd2b56ee3ef7a6ab48b03070 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Wed, 22 May 2024 21:31:32 +0200 Subject: nat: T6345: source NAT port mapping "fully-random" is superfluous in Kernel >=5.0 random - In kernel 5.0 and newer this is the same as fully-random. In earlier kernels the port mapping will be randomized using a seeded MD5 hash mix using source and destination address and destination port.
