I haven't been following this thread, and I appologize if this is redundant.
Could you do me a favor, and turn rp_filter ON, and ping the VIP with both
normal sized ping packets, and very large ( > MTU). And then, turn
rp_filter OFF and try it again?
I'm thinking this is the reason I was having trouble getting lvs-tun to work
with packets > the MTU. rp_filter is about the only proc entry I didn't
lookup and try fiddling with.
from the adv-routing HOWTO [1]:
".. if a packet arrived on the Linux router on eth1
claiming to come from the Office+ISP subnet, it would be dropped. Similarly,
if a packet came from the Office subnet, claiming to be from somewhere
outside your firewall, it would be dropped also."
I think LVS-TUN packets claim to be from the outside world, but come from
the subnet, don't they?
