Hello!
I'm using iptables v1.2.11 with kernel 2.4.26 at RH8.
Also there is squid-cache 2.5.STABLE1 listening at port 3128.

They works as transparent proxy gateway for small office:

[]# iptables -A PREROUTING -t nat -i LAN -p tcp --dport 80 -j REDIRECT --to-port 3128

to manage and account data going to 80 port I did something like this:
[]# iptables -A PREROUTING -t mangle -i LAN -p tcp --dport 80 -j LOG

the question is:
how can I manage packets incoming from 80 port to my LAN?
All chains and tables(OUTPUT:mangle,nat,filter and POSTROUTING:mangle,nat) shows that one go from local_ip_of_gateway:3128.
But tcpdump started at LAN interface shows that packets go from real ip addresses and src_port 80....
In what chain and table netfilter replaces SRC_ip & SRC_port back by real?

Thank you!
