        In 2.2 it is possible to run LVS with some patches
for the masquerade and the routing.

http://www.ssi.bg/~ja/#routes

        In 2.4 there are similar patches but they help only
netfilter to use multiple ISPs, LVS can not benefit from this
because the Netfilter hooks are designed not to hack the output
device. Simply, LVS requires hacking to fit in the netfilter
framework which is designed only for NAT. Using the routing without
the knowledge for following SNAT is a very bad idea and is the reason
for problems when using multipath routes. The solution? Of course,
someone to implement new NAT :)
