[Michlib-l] segmenting public and staff networks

[Helen Dewey]

Bruce,
I have been trying to find a way to separate the staff network from the public network, but I have not found a solution which lets us use only one broadband cable feed.  When I tried a switch and 2 routers (diagram I found online), the 2 networks were fighting each other for the Internet network feed.
I would greatly appreciate being pointed to information which would help me segment the networks.

Using your connection to pirate movies not only slows your network, but could land a library in hot water with the RIAA, who can report the activity to your internet service provider.


Even though our wifi requires no password, we do have a "captive portal" system in place to display our wireless policy. There are many other options to do this.

In the mean-time, you can dig into the settings in your wireless router. I believe you will be able to disable torrenting. Even though there are some legit uses for torrenting files, the vast majority is not traffic you want on your network, and you can possibly deal with exceptions as they come up (if they come up at all).

It sounds as though your staff machines are maybe using the same network connection and hardware as your public machines, and wifi. This could also create security headaches, and you have already seen with bandwidth needs for your ILS strained. Your network should be segmented, with each segment inaccessible to the other. This can be done virtually or physically. There are expensive and inexpensive ways to do it.

  We have been seeing a large increase in internet traffic and our wireless setup is simply not holding up. A particular problem is patrons using our wireless for torrents. Do any of you have policies in place regarding a limit on high-bandwidth activities? It is frustrating for our other patrons, many of whom are using the connection for schooling and business purposes, not to mention the staff trying to use VERSO.

  We currently have 6MB service through our provider (the highest package offered in our area) connected to an old router and switch. We have 5 public computers, one catalog computer, and one staff station all direct-wired through the switch and at any given time 2-10 wireless devices attached. Our current router is a Netgear N300 WNR2000v2. We're looking to upgrade and add a wireless access point to allow us better control, but that does not make our current situation any easier to handle.

  I've been setting the lowest priority QoS for the torrent users when possible to try to make the connection usable by other patrons. Does anyone have any tips on how we can better get by in the meantime?
