Thanks Amos, So I now have this for ebtables: :BROUTING ACCEPT -A BROUTING -p IPv4 -i eth1 --ip-proto tcp --ip-dport 80 -j redirect --redirect-target DROP -A BROUTING -p IPv6 -i eth0 --ip6-proto tcp --ip6-sport 80 -j redirect --redirect-target DROP -A BROUTING -p IPv4 -i eth0 --ip-proto tcp --ip-sport 80 -j redirect --redirect-target DROP and this for iptables: -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8080 -A PREROUTING -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8080 -A PREROUTING -p tcp -m tcp --dport 3128 -j REDIRECT --to-ports 8080 Still no go unfortunately. I'm pretty sure that the brouting interfaces are correct as they are, but just to make sure I flipped them around, restarted ebtables, and still had no luck. I just want to make sure I did not miss anything with my squid configuration. So, I have http_port 3128 transparent I attempted to use the following rules, however squid would have a cow and didn't want to start. httpd_accel_host virtual httpd_accel_port 80 httpd_accel_single_host off httpd_accel_with_proxy on httpd_accel_uses_host_header on In addition in /etc/sysctl.conf I have: net.ipv4.conf.default.rp_filter = 0 net.ipv4.ip_forward = 1 So, when I [root@squid0 ~]# cat /proc/sys/net/ipv4/ip_forward 1 [root@squid0 ~]# So I think everything should be good. Please let me know if you have any other ideas. Once again, thanks for your time! -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-DansGuardian-Bridging-tp4662202p4662292.html Sent from the Squid - Users mailing list archive at Nabble.com.
