can you please recommend an Virtual Appliance or Operating System for creating multiple site-to-site VPN?
The appliance must of course handle IPSec. It should also be OpenVPN capable. An Additional SSL VPN is a plus. It should run on normal virtualization servers like Xen and VMware. An easy to use Webinterface must be included. It is not required to be free but should start with very low pricing for small installations. Open Source solutions preferred.
P.S: Happy 100,000st question :)
