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
