Regarding real servers, if you have 2.6.5 or above, you don't need to
patch your kernel.  Just load the correct modules (unless you compile
the kernel yourself, in which case you determine if you need to
recompile to enable it) and set the right settings.  Here's my system
setup for our realservers:

webmail1 etc # tail -n 6 /etc/sysctl.conf
# For load balanced machines
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
