I spent - hopefully not wasted - several hours digging around today, trying to ease my own confusion, and I've kept half an eye on this for years. Luigi and colleagues first released versions if ipfw+dummynet under the name ipfw3 in early 2010 as near as I can tell. The naming is explained in the README at https://github.com/luigirizzo/dummynet which includes versions for Linux (2.4 and 2.6 at that time), OpenWRT and yes, Windows. Several other releases are at http://info.iet.unipi.it/~marta/dummynet/ all using the ipfw3 moniker. So perhaps that is the ipfw3 Kulamani is talking about, not wipfw? Further, https://github.com/luigirizzo/dummynet/blob/master/NOTES acknowledges that the windows port was originally begun from wipfw. If you google "ipfw3" (including quotes) you'll find references to your ipfw3 for dragonflyBSD, and plenty of references to *ipfw3.* archives of ipfw + dummynet sources and binaries as used with various Linux distros, questions about mostly the latter on lots of forums and lists .. This one is a good browse starting point, moving down or up the tree: https://www.cct.lsu.edu/~xuelin/dummynet/20100319-ipfw3/ipfw3/ for an early version. So I have to wonder whether you did much research before choosing a name for a different implementation? I guess that's too late to fix now, but let's try to be clear about differentiating two quite different things. cheers, Ian
