Problem restricting blog and RSS feed

Hi, I installed a wordpress blog that will be used for private use only.
To do this, I restricted access throw .htaccess file and allowed only a few ips (my intranet and 2 more fixed ips).
After doing this, RSS feed stopped working.
I need to make the RSS feed available also for those ips whitelisted. How can i do this? Because it works for “live bookmarks” on my Firefox, but when using a rss reader isn′t

Please, any help would be appreciated.

Thanks!
