yes

yes, I agree, the TP section is terrible, I'm rewriting it as we speak

yes, I've already fixed it.
then replace ", there

no, the problem is with the HOWTO. There's not much about 2.4 in the HOWTO yet
and in many places I just talk about the kernel without giving version numbers.
This just means I haven't written a 2.4 section yet and the info refers to the
2.2
kernels.

that's the script for the 2.2.x kernels (I've made that clearer too).
I haven't done transparent proxy for 2.4.x kernels yet, but I believe
the command will be something like
iptables -t nat -A PREROUTING -p tcp -d $VIP --dport $service --sport $service
-j REDIRECT
