Separate Guest VLAN but captive portal only in default VLAN; ZD1100

We've got a ZD1100 at one of our sites and a ZD1200 at the other. The site with the ZD1200 has the Guest WLAN on a separate VLAN and works perfectly.

However, I've tried to separate our Guest WLAN onto a separate VLAN at our site with the ZD1100 and even though the configuration is virtually identical:-

DHCP works all the way back to the firewall that provides DHCP;
yet users aren't redirected to the captive portal.
Users can access the captive portal by typing the IP address;
but once authenticated, users' traffic isn't showing up on the firewall's policy monitor.

How does the captive portal redirection work - what could cause it not to work on a different VLAN? (Works fine on our ZD1200 network with a newer firmware)

Once on the VLAN and authenticated, I would have thought we'd have no trouble accessing the Internet through the firewall (which is also the gateway address on this VLAN).

Any help/thoughts would be much appreciated!
