The ipvs folks are doing IP level load balancing with inverse masquerade

[MASQ]
+------+--------+-------+-------+------+
www1 www2 www3 www4 www5 www6
incoming SYN frames create masquerade sessions mapping user->www to user->www1
www2, etc according to load and rules.
In one mode they set things up differently as follows

MASQ www www www www www www
www1 www2 www3 www4 www5 www6
Each host is www and a unique name. The masq host arps for www, then
tunnels the packet to a www[1-n] but without rewrite. The reply doesnt touch
the masq so is a lot faster.
However they need to stop www1->wwwn arping for their www tunnel address
