Hi,
I managed to configure the different parts, but the DHCP server is not working on the LAN interface, I need some help. Here are my configuration files.

You only have a DHCP server configured for the main lan. But there are some odd things going on in general.

Would you mind posting the configs again... this time in the text config style (rather than the UCI style)... I find that easier to read.

Please copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

First of all remove all the gateways from the lan/lanpublic/lanprivate interfaces.
Then you cannot have multiple wan interfaces without some fixes.
What are rai* and ra* interfaces? Some wifi?
