[Openvpn-users] creating redundant VPN servers

Hi Everyone.

I would like to build a redundant OpenVPN system.  In the past I have used
Linux-HA and heartbeat with a virtual IP.  OpenVPN can use the --remote and
remote-random options to allow clients to load-balance/failover -- this
looks like a great feature.

With a single OpenVPN server clients come into the private network and
connect to an internal server.  The internal server has a route pointing to
the OpenVPN network (10.8.0.0/24 the example used in the docs).  This part
is easy.

With two OpenVPN servers I would need to have routing entries pointing to
each of the VPN servers.  When both VPN servers are active how does the
internal server know which VPN server to send the response to?  

Thanks,

Geoff
