I have a question that I have not found a definitive answer on, but am hoping someone here can chime in and either point me in the right direction or crush my hopes and dreams.
I have a Cisco ASA 5520 at an office. At a couple remote sites, there are linux boxes functioning as the network gateway/firewall. Is there a way to create a site-to-site VPN from one of those linux boxes to the ASA or will an investment in another ASA be required to achieve this?
