I've searched this forum and others for some advice, but haven't found any applicable tips yet for my situation. (I very likely overlooked relevant posts, so feel free to point me in the right direction. This is my first Aruba setup, so bear with me.)
I've run into DHCP and VLAN issues. I can see my SSID, but when I connect I get an automatic private address in the 169.x.x.x range. Basically, I want my campus Windows 2008 DHCP server to pass DHCP to my wireless clients instead of using the built-in DHCP server on the Aruba controller. My controller IP address is on VLAN 4, which is the same VLAN as my DHCP server. I want my wireless clients to be on VLAN 38.
On the Configuration tab, under Network>IP>IP Interface do I select "Use the following IP address" and enter the router IP address for the wireless VLAN? My wireless VLAN ID is 38 and the interface on my core router is 172.18.38.1. I entered this address and subnet, along with the DHCP Helper Address for my DHCP server, but my APs continuously rebooted, and I could not connect to the SSID. So I changed to "Obtain an IP address from DHCP". The APs stopped rebooting and let me connect to the SSID, but now I get the 169.x.x.x address.
