we are using Office Extend in our business for home offices. Until recently we deployed LAP1140 for this. Now with the End of LAP1140 and the much cheaper OEAP600 we wanted to test them. Those have the advantage of additional switchports which the user can utilize. You can also connect an IP phone to the enterprise switch port, which then gets tunneled through the DTLS connection to the WLAN Controller.
During that I came across the local DHCP server within the AP. It offers the network 10.0.0.0 /24 on the local switch ports as well as the personal SSID. In fact it introduces another subnet into the home network. This is a very unfortunate, given the broadcast / multicast based services running at home (Media Servers, iOS sync etc).
My question is: Can I configure the AP for DHCP passthrough on the personal SSID and switchports? So I may use the DHCP server that is somewhere within the home network?
Yes, Unfortunately this OEAP600 allow us to do very basic configurations (create local DHCP, personal SSID) on AP itself. Via WLC we can do few other paratmeters, but nothing to fulfill your requirement.
With WLC software code 7.5 onwards they have added a feature called "Split Tunneling" (configured via WLC) to access your OEAP-600 local switchport connected devices while you are connecting to corporate SSID. But again this is ONLY for printing service (port forwarding for certain print UDP ports) & not TRUE split tunneling. In your 1140 OEAP you can configure True Split Tunneling & not limited to printer service.
In that sense I would still prefer to use 1140 (if you could afford & no wired port requirement) as OEAP & create your personal SSID which it will be utilising your home DHCP server & you could enjoy services like AppleTV,ect. (not two network at your home)
