## Checking duplicates

```bash
$ for chain in INPUT OUTPUT FORWARD ; do echo $chain ; sudo iptables -L $chain -v | sort -u | wc -l ; sudo iptables -L $chain -v | wc -l  ; done
INPUT
21
24
OUTPUT

FORWARD

```

## Identifying duplicates

```bash
sudo iptables -L INPUT -v | sort
```


```
/sbin/iptables -A INPUT -i lo -s localhost -d localhost -j ACCEPTn
/sbin/iptables -A INPUT -i lo -j ACCEPT
```
