It looks good to me. The nice thing about using transparent proxying is
that it is a realativley simple way to get around the "arp problem" when
using Direct Routing. On the down side if your clients are running 2.2.x
kernels then even having transparent proxying compiled in has a performance
hit (that may or may not be an issue for you). If you want something to
read/do take a look at
http://linuxvirtualserver.org/Joseph.Mack/performance/single_realserver_performance.html
for a discussion of the performance issues.
