Default Setup WiFi DMZ

I want to setup a DMZ on my 3rd NIC port. I need to have a wifi DMZ for my TiVo to connect to the internet. I had this working okay by plugging my linksys wifi into the astaro DMZ port and I setup DHCP on Astaro. DHCP was disabled on the linksys. The problem with this setup is my kid's friends would come over with their iTouch and other toys and automatically connect to the DMZ and use up my 10 Astaro licenses. To get around this, I turned off DHCP on the astaro and turned it on in the linksys, but I can't get it to work. Here's my setup:

Interface: External WAN - goes to my cable modem
Type: Cable Modem (DHCP)

Interface: Internal (my main home LAN and works great)
Type: Ethernet Standard
Default GW: unchecked
Default GW IP:

Interface: DMZ1 (this is the one I am trying to get working)
Type: Ethernet Standard
Default GW: unchecked
Default GW IP:

Astaro DHCP on DMZ1
Range Start:
Range End:
DNS Server 1:
Default GW:
Wins Type: B-Node

I set this DHCP up in Astaro with a range of 1 because the linksys assumes the "router" is going to give it an IP. Just like it would if the Linksys was connected to a cable modem. I don't know if this is the right approach.

I have a cable going from the Astaro DMZ port to the Linksys Internet port.
Assigned Linksys IP:
On the Linksys I have DHCP enabled: -

The linksys is getting the IP (which normally would be a WAN IP) and default gateway from Astaro, but I can't connect to the internet. I tried changing the default gateway in the DMZ1 from to (same as the other interface), but this didn't work. I don't even know if you can jump across subnets like this.

What am I doing wrong?
