Hi

I am very new in configuring iptables with bridge software. I want to do a transparent proxy with iptables and squid and running a firewall bridge on the squid box. I have upgraded my kernel to 2.6.5 (to get the firewall-bridge) and I have already tried compiled iptables 1.2.9 with the kernel src directory. My problem is when I tried something like

/sbin/iptables -A PREROUTING -t mangle -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

or

/sbin/iptables -t mangle -A PREROUTING -m physdev --physdev-in eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

and iptables just return

iptables: invalid argument

Any help or pointer to some documents would be much appreciated.
