The ideal situation is that your browser on a PC (somewhere) is required to use a web proxy on your bastion server. The bastion trusts itself but blocks all 80/443 traffic from any other device. > The other problem is that *I* don't want to use the proxy and AFAIK > there's no way to identify users in iptables. If you're running the browser on the bastion box itself, there's --uid-owner and --gid-owner, but I have a feeling they are deprecated. Otherwise, could you configure your instance of the browser to use (say) port 63128 but for everyone else's to use 3128? Security through obscurity, as they say. Alternatively, configure squid to require authentication (I speak from bitter experience when I say this is horrible). > Setting up the browsers to use a proxy always seemed like a non-starter as > it's easily defeated. Not if it's the only way off the network. Just don't forget to block TOR and similar beasties. Chris

Eg for iplayer :- regexi ^http://www\.bbc\.co\.uk/iplayer/.* http://localserver/DontMessWivDad.html and/or 2. Use a bit of parental discipline backed up with a metal edged ruler. They'll soon get the message.
