+# Network setup for native sim firmware
+
+This folder contains documentation to provide a network setup suitable to run
+the native sim build of the firmware.
+
+It assumes a Linux host, an executable file with the native sim firmware,
+`systemd-networkd` as network configuration solution and `ufw` as firewall.
+
+For network configuration the `zeth.netdev` and `zeth.network` files from this
+folder have to be used with `systemd-networkd`.
+
+The following is required to open the firewall for the firmware on the `zeth`
+virtual network interface created by `systemd-networkd`:
+
+```
+ufw allow in on zeth to any port 1883 proto tcp
+```
