: No, they don't... they just LOOK like they do due to the inherent nature of : emulation. No packets actually pass from one network to another, so there : can be no "rewriting". (from a user's point of view, maybe it doesn't : matter). Joe. I'm sorry, but I have been working on on TIA as a consultant for the past 10 months. The UDP packets have their headers rewritten and sent out. The TCP packets are, indeed, batched up, but IP addresses in the data streams of TCP and/or port numbers are hacked along the way. TIA (and SLiRP) are the ultimate filtering firewalls. My probings of SLiRP show it to be doing the same sorts of things. Maybe I'm missing something here, but why doesn't that qualify as rewriting? Or are we having a semantic arguement? Warner
