+1. Enable ip forwarding:
+     ```
+    sysctl -w net.ipv4.ip_forward=1 # IPV4 Support
+    sysctl -w net.ipv6.conf.all.forwarding=1  # IPV6 Support
+     ```
+2. For persistent configuration: 
+    ```
+    cat > /etc/sysctl.d/99-sysctl.conf << EOF
+    net.ipv4.ip_forward = 1
+    net.ipv6.conf.all.forwarding=1

 ## Notes
 * A few people has experienced issues with running the dockerized method using bridged networking. To fix this, you can use `network_mode: host`. Note that you can no longer reverse-proxy the web interface from reverse proxies such as [jwilder/nginx-proxy](https://hub.docker.com/r/jwilder/nginx-proxy/).
