I am setting up a single machine for use by children and want to filter their internet access using dansguardian. This works fine on my home network (where I still use ipchains) but for some reason the shorewall firewall script does not want to redirect internet access to dansguardian. I tried adding the redirect entry to the /etc/shorewall/rules file, but nothing. Everything works as expected when I force Mozilla to use port 8080 (dansguardian) or port 3128 (squid) as proxy ports, but that's missing the point. I want it to be transparent.
Any suggestions? Nelson
