OK. So I should _not_ set up a "lo" device. OK. So instead I'm going
to set up a tunl0 interface instead with these parameters (i.e.,

and a RIP of 66.98.186.73. Does this look sane?
MTU=1480
I think you set the MTU on the sending end (at the
director). It's too late by the time the packet
gets to the realserver. There's no reverse path
(from the realserver to the DIP) so ICMP packets
can't get back to tell the director that the MTU is
wrong. Look at the MTU writeup in the LVS-Tun
section of the HOWTO to be sure.
I expect it can't hurt to set the MTU here too.
NETMASK=255.255.255.255
BOOTPROTO=none
BROADCAST=66.98.1.255
BROADCAST=66.98.227.143
wierd isn't it? This is a /32 network.
IPADDR=66.98.227.143
NETWORK=66.98.227.143
ONBOOT=yes
DEVICE=tunl0
