Now that I've got IP masquerading set up with linux and netfilter, what I really want is for tools like etherape and ethereal to be smart enough to show me sources and destinations on both the inside and outside of my network. For instance, both tools can show me packets coming to my box on both interfaces, and where my box sends them, so why can't a tool be smart enough to show me a source and destination with my box removed? Then I could do nice things like determine who hogs bandwidth and for what.
