You need a proxy IP for this. The server 192.168.1.2 acts as client
as well. The request from 192.168.1.2 will go to IP address 10.0.0.10
on port 4444. It is getting load balanced to the only existing real
server which is again 192.168.1.2. The real server is getting a
request from 192.168.1.2 now (its own IP address). It will try to
answer directly and therefore the return traffic is not getting
translated back again to 10.0.0.10. The real server is talking to
10.0.0.10 but the reply would come from 192.168.1.2 - BOOM - not
working. There is no other solution then a proxy IP from my point of view.
