Dodgy Network Simulator

Does anyone know of gateway or proxy software you can install on a machine to simulate a bad network – i.e. it routes packets from one interface to another but drops, delays or rearranges them in a configurable way at the same time? I know Squid can do bandwidth limiting, but ideally I need the other things too.

Unsurprisingly, it’s for testing a product over a dodgy network connection.

  1. NIST Net looks like it hasn’t been updated since 2001. Has anyone used it recently? Does it still work? Are packages available?

  2. As mentioned above, a FreeBSD machine running dummynet should allow you to do this!
