Task Plan IP addressing, VLAN and management deployment for a small WISP deployment We intend to use a combination of Mikrotik and Ubiquiti hardware with DMA softlab and Ubiquiti Wifi management software to deploy our public wifi network. The general plan: Provide Ubiquiti equipemt at customer premesis, this will be done in one of three configurations a. Long range Wifi - directly in to customer equipment b. Long range Wifi --> managed switch --> Hotspot & Customer equipment c. Long Range Wifi --> managed switch --> Hotspot, Customer equipment and managed internal wifi AP. I have drawn a configuration of how I would deploy it, however I am looking for someone with IP networking experience to advise on the plan and change if required. At the client end the following equipment to be installed: - Long range wifi (could be one of a few different models, but in the Ubiquiti range so the configuration will be the same/almost identical). This will provide a link between the main link, and their premises. The configuration of this device should only be viewable on the management VLAN (client should not be able to find/see this device) - Long range wifi to connect to Ubiquiti tough switch. Management VLAN extends to tough switch to enable management. - Access point to connect to toughswitch to provide wifi access throughout the house. Plan requirements: Proviide a general network configuration that can be applied to each of the above scenarios and then can be replicated as more customers sign up. Plan should include - IP ADDRESSING - Mikrotik Router configuration - VLANs - Ensure separation of public network and each client's network - A management network that can view base equipment, customer Long range, customer tough swtiches, and customer AP's (which will be centrally managed). - Ubquiti equipment configuration (IP, VLAN, etc) - Whether Long range AP is to provide DHCP or done by Mikrotik at base - No client can access management network
