Hi,
Because of the performance advantages of LVS-DR, the fact that I'm already
familiar with the LVS-DR setup, that it doesn't require any special setup
when realservers themselves want to contact load-balanced services and the
fact that I can keep all the routing/firewalling/balancing on the systems
that are dedicated to that role anyway.
The only thing I really need at this point is a way to say "if you see a
packet with IP X (vip) as source on (internal network) interface eth1 then
don't apply the martian filtering".
Regards,
Dennis
