for LVS-Tun you don't setup a tunnel. LVS makes its own ipip
packet and forwards it through the regular ethernet device
on the inside of the director to the tunl0 device on the
realserver.
Hi Jason,
Don't know if you're up for messing with LVS-Tun or
not. The poster this morning couldn't get LVS-Tun to work
because he'd set up a tunnel between the director and the
realserver. He didn't need to do this because LVS creates
its own ipip packet. If you hadn't read the HOWTO, it would
have been reasonable to do what the poster did. It occurs to
me that LVS should be letting the kernel do as much as
possible, and ip_vs() should let the kernel handle the
tunnelling and we should have the users set up a tunl0
device on the director. I think this would allow PMTU
packets to come back from the realserver to the director
too.
Anyhow just a thought
Joe
