Iptables configuration for a transparent proxy for a single user

[leandro noferini <lnoferin@xxxxxxxxxxxxxxx>]

Ciao a tutti,

in tor wiki at the address

http://wiki.noreply.org/noreply/TheOnionRouter/TransparentProxy#head-235f10e71909d609c46847c9f91efe8ed5168004

explains the way to apply a trasparent proxy for a specific user.

The rules for iptables are 

iptables -t nat -A OUTPUT -p tcp -m owner --uid-owner anonymous -m tcp --syn -j REDIRECT --to-ports 9040 
iptables -t nat -A OUTPUT -p udp -m owner --uid-owner anonymous -m udp --dport 53 -j REDIRECT --to-ports 53 
iptables -t nat -A OUTPUT -m owner --uid-owner anonymous -j DROP

In my debian  unstable linux (kernel 2.6.29 and  iptables 1.4.3.2-2 from
package) these  rules don't  work anymore and  this is the  message from
iptables

The "nat" table is not intended for filtering, the use of DROP is therefore inhibited.

Does anyone know the changes needed tomake it work again?
