+### Persistent IP tables
+
+* <https://packages.debian.org/trixie/iptables-persistent>
+
+The rules you have set are temporary and will be lost on reboot. To make them permanent on Debian 13, you need to use the `iptables-persistent` package.
+
+First, install the package:
+
+```
+sudo apt-get update
+sudo apt-get install iptables-persistent
+```
+
+During the installation, you will be prompted to save your current `iptables` rules. Make sure to confirm "Yes". If you are not prompted, you can manually save the rules with these commands:
+
+```
+sudo iptables-save | sudo tee /etc/iptables/rules.v4
+sudo ip6tables-save | sudo tee /etc/iptables/rules.v6
+```
+
+The `iptables-persistent` service will automatically load these rules at startup.
