Running `xtables-legacy-multi` without any arguments produces 
output stating that it requires a subcommand, 
e.g. `xtables-legacy-multi iptables-legacy`. Running _that_ 
results in:

```
iptables v1.8.11 (legacy): no command specified
Try `iptables -h' or 'iptables --help' for more information.
```

So what happens if you instead do:

```
exec("/usr/bin/xtables-legacy-multi iptables-legacy -L COUNT -n -v 
-x -w", $iptables);
```

?
