Wireless client on LAN

Installing and Using OpenWrt
1

Hi,
Struggling to get the following working on a BT HomeHub5A running OpenWrt 24.10.0

I want to use this router to connect some IP cameras monitoring some buildings. It will connect back to the home network over WiFi. There is an outdoor WiFi access point to connect to.
I've been trying to have the IP cams on the WAN. Also on the WAN I have the 2.4GHz radio as an access point for WiFi IOT devices. I'd like the LAN side just just simply connect back to the main network. Most tutorials online only discuss this for WAN with a Client connection. I've had this work when set the radio to WAN but never LAN. I could quite happily have a static IP but I can't work out how you would do this. Put an IP on the LAN interface and then an ad-hod wireless connection? I can cope with static or DHCP IP for this connection.
In summary, should this be possible? Is it posible to have radio0 on the LAN and radio1 on the WAN is another question I have. Could there be something in the default firewall rules that would stop the DHCP connection on the LAN side?

Any advice gratefully received.

You will need ip address per camera from your provider, and in 30s on the internet they will be hacked.

Thanks for coming back.
Sorry, I haven't been very clear.
The cameras are wired connections into the OpenWrt router. While they are on the 'WAN' side of the router, it is just a private network. I was trying to use OpenWrt as close to 'out of the box' as possible as default LAN/WAN config is close to what I want. In truth, this is LAN1 to LAN2 but with LAN/WAN firewalling and NAT. None of this is on the Internet.

You should be able to add guest network on primary router.

I still need to solve how to get a wireless client to work when not on the WAN side of the remote router

Hmmm. I guess I'll start with this https://openwrt.org/docs/guide-user/network/wifi/relay_configuration and see if I can progress from there.
