Another brand new model to get a remote AP still using CAPWAP with FlaxConnect and OEAP (OfficeExtend AP) feature. On this way, you just need a WLC centralized in a DMZ (Internet access) to set a remote AP over internet (any flavor eg. ADSL) to get the WLC profile and auto set a security tunnel (using DTLS). No firewall, no remote switch or corporate router to register a Lightweight AP in the remote WLC over a security tunnel.
