From d9e7522b561ceb323e93affb29c9fced89fed967 Mon Sep 17 00:00:00 2001 From: Lorenz Stechauner Date: Thu, 5 Aug 2021 12:59:03 +0200 Subject: [PATCH] fix #2721: remove reject tcp 43 from default drop and reject actions first, '43' is a typo, it should say '113' (if it really is like legacy shorewall [0]). this tcp port corresponds to the ident or authentication service protocol. second, nowdays this reject is not included in shorewall anymore. furthermore it would make no sense to reject specifically this one port.
