Package: iptables-persistent Severity: normal I had an existing /etc/iptables/rules.v4 file on my system. In the next step I installed "iptables-persistent" and said yes to both questions about saving current existing rules.
Then the file and my rules in it where gone. That shouldn't happen. When you want to touch that file that add content to it but not overwrite it. -- System Information: Debian Release: 11.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-18-amd64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages iptables-persistent depends on: ii debconf [debconf-2.0] 1.5.77 ii iptables 1.8.7-1 pn netfilter-persistent <none>
