## Enable IP forwarding

IP forwarding allows the routing of packets between networks. To enable IP forwarding on your WireGuard server, use the below command to open the configuration file:
IP forwarding allows the routing of packets between networks. This allows internal devices to communicate with each other through the WireGuard tunnel:

```bash
sudo vim /etc/sysctl.d/99-sysctl.conf
```

Add a rule for IP forwarding. Turn on IP forwarding for IPv4 and IPv6. This allows internal devices to communicate with each other through the WireGuard tunnel:

```bash
net.ipv4.ip_forward = 1
net.ipv6.conf.all.forwarding = 1
```

Apply these configuration changes with:
Turn on IP forwarding for IPv4:

```bash
sudo sysctl -p
sudo sysctl -w net.ipv4.ip_forward=1 && sudo sysctl -w net.ipv6.conf.all.forwarding=1
```
