While the above diagram is highly simplified it represents what I am trying
to achieve. These two sites (and eventually another remote site) will
eventually run FreeSWAN to establish a private tunnel between the real
servers so the reserved IPs e.f.g and e.f.h are different on purpose.
The Home site uses VS-TUN since all realservers can route out.
The Remote site uses VS-NAT since the realservers can only route via LVSB.
All incoming requests go to LVSA. LVSA decides to route to its own cluster
or redirect to LVSB.
How do I load-balance/redirect between LVSA and LVSB?
