Wes and Aaron have covered it. I just want to say it a different way.

You want everything connected through the ZyXEL to be separate from the 
machines already connected to your home router (the home LAN).

Everything connected to the ZyXEL will come from the ZyXEL to the home 
router over a single ethernet line. The home router is responsible for 
isolating the home and ZyXEL traffic. The ZyXEL just functions as a WAP. 
There's no special routing on the ZyXEL. If your home router has multiple 
ethernet cards (eg it's an old repurposed PC, my preferred type of 
router), then you can attach the ZyXEL to its dedicated ethernet card on a 
separate network on the router. Otherwise you'll have to VLAN the ports on 
the LAN side of the home router (which is beyond me).

The WAN port on a WAP is to connect directly to the internet and to use 
the WAP as a router. I want my own router with iptables etc. I don't use 
the WAN port on a WAP. I connect one of the WAP's LAN ports to the home 
router. The LAN port will have an address of 192.168.0.1 (or something 
like that). Move it to an address that matches the network on the port on 
the LAN on the home router that the ZyXEL will be connecting to. Write 
that address on tape on the body of the WAP, as you'll need to know it to 
access the WAPs config page in the future.

Next get the WAP working. Turn off dhcpd on the WAP as the WAP clients 
will now be getting their dhcpd from the home router. Set an SSID on the 
ZyXEL. Clients should now be able to connect through to the home router. 
Then on the home router, isolate the wire going to the ZyXEL (if needed).
