<p class="MsoNormal">Just wondering if anyone has recommendations on a virtual appliance (VMWARE / Xen compatible) which can terminate xx000's of roaming clients. Hoping to support ipsec ikeV2 + openVPN. I've been looking at Vyatta, strongswan & openVPN server.
Wondering if anyone has experience good or bad to share on these platforms? Or other recommendations?<o:p></o:p></p>
