We have several offices, with Firewalls on each site. The sites are connected via VPN. So we decided to work with IAPs without controller. We have an Airwave Server installed on one site. This works fine without any problems.
Want we want to do: we have some guest houses, which have no firewall and no VPN connection to the main building. We want to radiate our company WLAN at the guest house. We are also looking for a solution to radiate the company WLAN in changing locations like tech fairs, customer sites, etc.
