[tproxy] Clarification on tproxy4 usage

Hello, Some clarification on tproxy4 usage: I am using the following on kernel 2.6.25: tproxy-kernel patch: tproxy-kernel-2.6.25-20080519-165031-1211208631.tar.bz2 tproxy-iptables patch: tproxy-iptables-1.4.0-20080521-113954-1211362794.patch I followed all that is given in http://www.balabit.com/downloads/files/tproxy/README.txt The patches have got applied successfully and with Squid-3.HEAD, w00t, I am able to see the full transparency functionality. However, SNATting the traffic in NAT - POSTROUTING chain ends up in vain. Is this the intended behavior or am I missing out anything? TIA -- Regards, Arun S.
