I asked this on Meta a few years ago, discussing whether or not [home networking questions][1] were on-topic, and we came to the conclusion it was. A good example of a good on-topic question like this can be seen [here][2].

Of all the SE sites, I feel Super User is probably the most on-topic for that question. It may benefit from being worded a little better, and perhaps a diagram of what is trying to be achieved could help out as well.
