Horms,
As I know, the lvs director with NAT rewrites the destination IP
address for incoming packets and rewrites the source IP address for
outgoing packets. Thus real server must set lvs director as default
gateway.
Now I wonder if the lvs director can rewrite both destination IP
address and source IP address for all packets. Example, director
replace the destionation IP address with real server's IP address and
replace the source IP address with director's private address.So real
server don't have to set director as default gateway. Can lvs do it?
Thank you
Couldn't this be done at the netfilter level. Setup NAT on the
outbound traffic for the inside interface. Kinda a reverse NAT for the
Internet. Inbound traffic gets load balanced by LVS-NAT (i.e. the
source stays the same but the destination becomes the real server).
Gets routed out the LVS box and hits the netfilter NAT setup and gets
NATed (i.e. the destination stays the same but the source gets
rewritten to that of the LVS internal IP). The real server gets a
packet from the LVS. This would eliminate any useful information in
the logs but it should work.
