+Simplyblock requires a number of TCP and UDP ports to be opened from certain networks. 
 
-Following is a list of all ports (TCP and UDP) required for operation as a storage node. Attention is required, as this
-list is for storage nodes only. Management nodes have a different port configuration.

+    The identical nvmf ports are TCP for NVMe-oF/TCP and UDP for NVMe-oF/RDMA.

-    The example assumes an external firewall between the _admin_ network and the public internet!<br/>
-    If this is not the case, ensure the correct source access for port _22_.
-
-```bash title="Disable IPv6"
-sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
-sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
-```
-
-Docker Swarm, by default, creates iptables entries open to the world. If no external firewall is available, the created
-iptables configuration needs to be restricted.
-
-The following script will create additional iptables rules prepended to Docker's forwarding rules and only enabling
-access from internal networks. This script should be stored in _/usr/local/sbin/simplyblock-iptables.sh_.
+Script to apply firewall rules using iptables:
 
 ```bash title="Configuration script for iptables"
-#!/usr/bin/env bash
-
-# Clean up
-sudo iptables -F SIMPLYBLOCK
-sudo iptables -D DOCKER-FORWARD -j SIMPLYBLOCK
-sudo iptables -X SIMPLYBLOCK
-
-# Setup
-sudo iptables -N SIMPLYBLOCK
-sudo iptables -I DOCKER-FORWARD 1 -j SIMPLYBLOCK
-sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT
-sudo iptables -A SIMPLYBLOCK -p tcp --dport 2375 -s 192.168.10.0/24,10.10.10.0/24 -j RETURN
-sudo iptables -A SIMPLYBLOCK -p tcp --dport 2377 -s 192.168.10.0/24,10.10.10.0/24 -j RETURN
-sudo iptables -A SIMPLYBLOCK -p tcp --dport 4420 -s 10.10.10.0/24 -j RETURN

-To automatically run this script whenever Docker is started or restarted, it must be attached to a systemd service,
-stored as _/etc/systemd/system/simplyblock-iptables.service_.
-
-```plain title="systemd script to set up iptables"
-[Unit]
-Description=Simplyblock Iptables Restrictions for Docker
-After=docker.service
-BindsTo=docker.service
-ReloadPropagatedFrom=docker.service

-```
-
-After both files are stored in their respective locations, the bash script needs to be made executable, and the systemd
-service needs to be enabled to start automatically.
+#!/bin/bash
 
-```bash title="Enabling service file"
-chmod +x /usr/local/sbin/simplyblock-iptables.sh
-systemctl enable simplyblock-iptables.service
-systemctl start simplyblock-iptables.service
