[lvs-users] one real server in LAN, another in the internet - possible?

Is the following setup possible with LVS:

real server (same LAN)
/
user -- internet -- load balancer
\ real server (in internet)

?

I tried to set this up with LVS/NAT, but only could connect to the real
server which is in the same LAN as the load balancer.

Is it possible to have the real server somewhere in the internet with LVS?

I have three real servers in the same LAN as the load balancer and one
on the Internet. I use DR mode for the three and tunnel mode for the
one. They have been working well for me for a year so far.

is the director the only route for packets from the
internet realserver to the clients?

if you set up the director as a NAT box (rather than LVS
director), can you get to (using NAT) your internet
realserver from a client on the internet?
