"Why do I get a 403 error when trying to use Gii?"
Revision #6 was created by 
Noted that Yii 1.1.6 essentially fixed this issue.

```The `ipFilters` property can include as many items as you like, and they can be straight IP addresses or wildcards such as `"192.168.1.*"`.
IPv6 addresses are supported as well if the underlying platform supports it, and `"::1"` represents localhost (which may be required in some configurations).
Be careful not to open Gii to a too-wide audience lest it become a security risk.
Note: Yii 1.1.6 adds the default filter directly to the stock config file:
```php
// If removed, Gii defaults to localhost only. Edit carefully to taste.
'ipFilters'=>array('127.0.0.1','::1'),
```
so this FAQ may not be so frequent much longer.
