This is undoubtedly off-topic in oh-so-many ways; I'd be quite happy to be redirected to another, more appropriate mailing list should someone be so kind as to suggest one. Internal, home, private network, WinXP boxen and a Squid proxy, connecting through an iptables box to my router and cable modem. Everything works peachy. While trying to poke bittorrent holes through my iptables setup (see? Some vague evidence of relevance), I encountered problems and decided to take the proxy out of the picture. VERY much to my surprise, when I reconfigured IE to not use the proxy (and configured iptables to allow for a direct connection), I see no HTTP traffic whatsoever leaving the XP box destined for the firewall. In fact, no TCP traffic either (all traffic analysis done with ethereal on the XP box). I can ping to/from the XP box, and see THAT via ethereal. I am considerably confused by this. My presumption was that IE would just happily send HTTP traffic directly to the firewall, but this is NOT the behaviour I'm seeing. I know it's Christmas Eve day, and I was out a bit late last night, but there's clearly something VERY obvious I'm missing.
