The problem ("this") is each real server would need to
be able to have its default gateway (default route?)
set to the NAT ROUTER IP, but trying it incorporate
two live directors means dealing with two NAT Router
IP's,
and I don't see (or know how) I could get the real
servers to route back to either NAT Router IP based on
which LVS IP the packet came in on. That's where I
started to think about 2 NICS in each real server, and
started to ponder multiple default gateways, and if
there was any light at the end of this tunnel. Like
this:
2 NICs in ea. RS.
Each NIC shown by "="
DIR1------ =|REAL
\ ---- =|SRV1
\/
/\
/ ---- =|REAL
DIR2------ =|SRV2
This diagram representing two NAT Router IP
addresses on the two live Directors.
It's the network setup of this on the Real Server side
that is concerning me.
Thanks
