      I will grant you that the attack is extremely unlikely either against DNS or DHCP, but considering it takes seconds to setup, I don't see the harm in it either. Coupled with the already stated fact of the Windows licensing makes it a requirement in my case since I don't want to setup completely separate APs for guest access.

      Takes seconds? You are having nothing but issues because of wanting a VLAN.

        Thanks - it's true I have a current issue, that's related to VLANs - but this guest network is not one of them. That was installed and working in only seconds longer than it would have taken if I didn't have a VLAN. my current issues are around a legacy network.

          Wasn't this thread started because you couldn't get it to work?

            If it only took seconds, took nothing to maintain, added no complexity to the network and was just as easy to hand over to someone else, then I'd agree.

              No, that thread - where I am still having problems - is because I can't get my phones to work on their designated VLAN - has nothing to do with Guest access.

                Ah ok. I just have a hard time believing you set up firewall ACLs and switch interfaces in a few seconds.

                  The title of this thread was also not my intention in this off shoot discussion.

                  The purpose was to show that using corporate resources could lead to problems on the corporate network.
                  In the case of the college, their dedicated IOT network was using DNS from their corporate network. This IOT network was dedicated for college resources - like vending machines and street lights, etc. Over 5000 devices.

                  My intention was more about how an infection on a guest network with access to corporate resources, COULD effect those resources, and as such, simple mitigations could solve this issue.

                    Well you brought it up in the context of a small medical office and that's what we were responding to. This thread started specifically about that and it was @JaredBusch that started it. So that IoT stuff is out of scope. You could have ANOTHER thread about IoT dangers, but that's unrelated to what Jared and I were discussing with you.

                      Then it wasn't dedicated 😉

                        No, clearly it wasn't dedicated.
