RouterOS (on Routerboard hardware, or on x86 hardware) is pretty
flexible with config - although I have never read or seen
experiences of it with VPN clients in that number of connections.<br>

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<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>
