    Hey Blake,

    You said something about the muni wifi offering a different price for users with a router, rather than a single device…

    Any idea how they enforce this?

    I can think of two ways to tell whether a user has deployed a NAT box with multiple machines behind it, neither of which lend themselves very well to enforcement:
    – different TTLs in outgoing packets
    – different IP ID numbers from inside systems

    My best to AJK, and congrats!

      To be honest I don’t think they really are enforcing that here. The difference in price is because they give you a Wireless to Ethernet bridge, so I’m assuming that they have the price adjustment as you are renting a piece of equipment from them. You are correct though in that there really isn’t a good way to enforce this. Cellular providers look for people cheating the hotspot system by looking at TTLs typically. Even with systems in place like ISE/ClearPass it still would be tough to enforce.
