We have two WLC 5508 and i want to know if it is possible to get an accesspoint ( eg. 1131) to connect to a controller over internet, without VPN-connection. I have read documents about HREAP but that needs, if I understands it correcly, a VPN tunnel or a dedicated WAN-link. I know that ARUBA has this function, but I cant find it with CISCO.
Yes you can. You would have to use the 1131 as an OfficeExtend AP. At least this way you can encrypt your data traffic unless you are in Russia. Take a look at the AP600 OfficeExtend configuration guide. This will show you how to setup your wlc and your SSID.
