From 289c46869b969864676cf9abde4e1e0df33bcf37 Mon Sep 17 00:00:00 2001 From: Alin Nastac Date: Wed, 8 Jun 2022 11:58:00 +0200 Subject: [PATCH] 464xlat: delete SNATed conntracks on interface teardown Existing conntracks will continue to be SNATed to 192.0.0.1 even after 464xlat interface gets teared down. To prevent this, matching conntracks must be killed.
