From 0eaf4e6784efb2d058fe2f031578251b6bcc0aa8 Mon Sep 17 00:00:00 2001 From: Filip Varga Date: Wed, 17 Feb 2021 14:34:54 +0100 Subject: nat: Final NAT44 EI/ED split patch This patch achieves complete separation of endpoint-dependent and endpoint-independent IPv4 NAT features. Some common stuff is also moved to NAT library.
