+You can get this error on reload or restart. Try deleting the .start, .restart or .reload files in ///var/lib/shorewall///. They will get regenerated on next ''shorewall start'' or ''shorewall restart''
+===== Changes from rules.d directory are not reflected upon reload/restart =====
+If you are adding rules to ///etc/shorewall/rules// file via [[https://shorewall.org/configuration_file_basics.htm#Embedded|embedded shell command]] i.e.
+  ?SECTION NEW
+  SHELL cat /etc/shorewall/rules.d/*.rules 2> /dev/null || true
+and the changes are not applied make sure that ''AUTOMAKE=No'' in ///etc/shorewall/shorewall.conf//. Check the [[https://manpages.debian.org/unstable/shorewall/shorewall.conf.5.en.html|man page]] for other possible values.
