Nick,
Heres what we're using:
* Kernels patched with ipvs 0.8.3
* Kernels patched for the arp problem using
http://www.linuxvirtualserver.org/sdw_fullarpfix.patch
* Realservers configured to listen for VIP on tunnel device
(specifically tunl0:0)
* Director configured to listen to VIP on ethernet card. (specifically
eth0:0)
(If it's not obvious we're using the same kernel on all the machines to
improve flexibility of our setup)
Michael.
