Trying to use the policy drop rule with the bridged firewall, when I removed the first line the transparent proxy works great? It seems a bit strange as from reading several articles on it I thought the following occurs. 1st line - if it doest match it gets dropped on the local filter input. 2nd line - redirects the traffic off the link layer into the network layer ready for line 3. 3rd line - redirects the port 80 to 8080 and then goes to the local process (squid) through the input filter 4th line - input filter accepts the traffic over riding the global reject policy. iptables -P INPUT DROP ebtables -t broute -A BROUTING -p IPv4 --ip-protocol 6 --ip-destination-port 80 -j redirect --redirect-target ACCEPT iptables -t nat -A PREROUTING -i br0 -p tcp --dport 80 -j REDIRECT --to-port 8080 iptables -A INPUT -p tcp --dport 80 -m physdev --physdev-in eth1 --physdev-out eth0 -j ACCEPT Any help would be most welcome.
