E4200 Guest SSID Login page fails

Question

Config:
Netgear ProSafe Gigabit Router is my DHCP Server -- The entire home net work is on the same subnet (192.168.15.xxx)
Linksys E4200 configured as an access point ONLY -- wired connection -- static IP assigned -- DHCP server turned off
Linksys WRT610N configured as an access point ONLY  -- wired connection -- static IP assigned -- DHCP server turned off
3 -- 5 port gigabit switches
1 -- 8 port gigabit switch
No more than two switches between any two wired devices
Both Linksys access points have the same SSID and WPA2 security phrase -- total of 4 radios
Nonoverlapping channels are selected on both the 2.4Ghz and 5.0Ghz radio to minimize interference
All computers are running Windows 7 Professional 64bit with all the latest updates
Two iPhones and one iPad also access the network
All LAN and WAN connectivity is working as designed
Problem:
guest SSID is turned on
password is established
All devices will connect to the guest SSID and the E4200 is assigning an ip address to the device in the 192.168.33.xxx range which is what it's supposed to do.
When I open a web browser, I am not automatically redirected to the Cisco Login Page. If I enter 192.168.33.1 as the URL, the login screen is presented. I enter the password I have created in the guest admin page on the wireless guest tab.  I then see a blank page and a URL of 192.168.33.1/guestnetwork.asp. THIS IS WHERE I GET STUCK. THE ONLY WAY TO EVER SEE THE LOGIN PAGE AGAIN IS TO REBOOT THE E4200, otherwise you just get unable to connect messages when opening web browsers and the wireless status icon in the system tray shows a yellow exclamation mark.
I successfully connect to the guest SSID but I do not get access to the internet. When I type ipconfig, I see that the DNS is set to 192.168.33.1 which does not exist on my network. I assume there's some internal NAT magic that is supposed to happen in the E4200 to bridge me over to my 192.168.15.xxx network but it doesn't seem to be happening.
At the beginning of the call I specifically asked them if the E4200 must be the DHCP server in order for the guest SSID feature to work and they said no. 1.5 hours later they had no answers so they told me that it wasn't working because the E4200 was not the DHCP server. The documentation says nothing about a DHCP requirement for guest AP service. Linksys support further could not answer what you would do if you needed more than one AP with guest service enabled.
It seems like this is a firmware issue but it may be the guest SSID service requires the E4200 to also act as the DHCP server. Can anyone shed any light on whether this is a bug or if the router/AP is working as designed?
Thanks,

Answer 1

Yes the E4200 must have DHCP turned on in order to pass out IP's to your Guest Network.  No DHCP, no Guest Network.
