kudos for all the hard work! Most of this should've been done a long time
ago as `pylint` is one of the first firewalls of code quality ensurance.
Side notes:
* no fan of `%s` syntax; recommend further refactoring to employ
`.format()` which should make the code a lot more elegant.
* Strings oughta be single-quoted unless double quotes are necessary
e.g.:
```
- self.fw.append(
- ["nat", "",
- "-I PREROUTING -i ppp+ -m tcp --dport 53 -j DNAT --to-destination
%s" %
- local_ip
- ]
- )
+ self.fw.append([
+ 'nat', '',
+ '-I PREROUTING -i ppp+ -m tcp --dport 53 -j DNAT --to-destination
{}'.format(
+ local_ip
+ )])
```
