cisco-webvpn-redirector от Lukas Botsch

Your company, institution or school uses a cisco webvpn portal? Then this add-on is for you! It adds a button to your browser that allows you to toggle between seeing the current page through a webvpn or seeing the original page.

Note: Configure your webvpn base url in the addon settings page. If your webvpn portal is located at https://my-company.com/+CSCOE+/portal.html, then set the base url to https://my-company.com/
