+## NAME
+podman\-network\-reload - Reload network configuration for containers
+
+## SYNOPSIS
+**podman network reload** [*options*] [*container...*]
+
+## DESCRIPTION
+Reload one or more container network configurations.
+
+Rootful Podman relies on iptables rules in order to provide network connectivity. If the iptables rules are deleted,
+this happens for example with `firewall-cmd --reload`, the container loses network connectivity. This command restores
+the network connectivity.
+
+This command is not available for rootless users since rootless containers are not affected by such connectivity problems.
+
+## OPTIONS
+#### **--all**, **-a**
+
+Reload network configuration of all containers.
+
+#### **--latest**, **-l**
+
+Instead of providing the container name or ID, use the last created container. If you use methods other than Podman
+to run containers such as CRI-O, the last started container could be from either of those methods.
+
+The latest option is not supported on the remote client.
+
+## EXAMPLE
+
+Reload the network configuration after a firewall reload.
+
+```
+# podman run -p 80:80 -d nginx
+b1b538e8bc4078fc3ee1c95b666ebc7449b9a97bacd15bcbe464a29e1be59c1c
+# curl 127.0.0.1
+works
+# sudo firewall-cmd --reload
+success
+# curl 127.0.0.1
+hangs
+# podman network reload b1b538e8bc40
+b1b538e8bc4078fc3ee1c95b666ebc7449b9a97bacd15bcbe464a29e1be59c1c
+# curl 127.0.0.1
+works
+```
+
+Reload the network configuration for all containers.
+
+```
+# podman network reload --all
+b1b538e8bc4078fc3ee1c95b666ebc7449b9a97bacd15bcbe464a29e1be59c1c
