IPv4 forwarding is disabled. Networking will not work
Solution 1: This won’t work every time
```shell
// run on host server
sysctl -w net.ipv4.ip_forward=1
sudo systemctl restart network
```
Solution 2: Append **net.ipv4.ip_forward=1** to **/etc/sysctl.conf** file.
Solution 3: Append parameter **—net=host** to **docker run**, that will use host ports and ignore the **-p** parameters for example:
```shell
docker run -it --network host –name mynginx nginx
```
