Guest network problem

Installing and Using OpenWrt
1

There seems to be something missing from my attempt to create a guest wireless network. My LAN is 192.168.2.0/24 and my guest should be 192.168.3.0/24. Looks like there's some sort of DHCP issue as clients can't connect to ESSID 'chinahouse' but i can supply info as needed. Firstly here are some config files.
TIA

I haven't done this since I started using LEDE a few years ago (am migrated over to OW). Someone more knowledgeable may reply. I am posting to see if you found this wiki page that might be helpful.

Have you bridged the guest network with the WAN interface!?

Thanks for the reply.
Well i was following a tutorial that said assign it to the WAN firewall zone. I thought that might bridge it 'automatically'. As it happens, WAN is not in the drop down.
Wireless Network: Master "chinahouse" (CHGuest)
is though.

I do not know why tutorial you where following, but you must not bridge the guest network to WAN, or even put then on the same firewall zone.

I would follow the "official" guide, as pointed out by @darksky.
