Additional SSID not working + OpenWrt revert question (GL-BE9300)

[will.qiu]

Thank you for providing the backup configuration file.

After reviewing it, we found that a required step appears to have been missed, which caused DHCP requests from devices to the IoT network to be blocked by the firewall.

After importing your backup to our local router and adding this step, devices connected to the IoT SSID were able to obtain IP addresses via DHCP.

7. Allow DHCP and DNS for IoT
Firewall rules are added to allow IoT clients to obtain DHCP leases and resolve DNS.

uci add firewall rule
uci set firewall.@rule[-1].name='Allow-DHCP-IoT'
uci add_list firewall.@rule[-1].proto='udp'
uci set firewall.@rule[-1].src='iot'
uci set firewall.@rule[-1].dest_port='67-68'
uci set firewall.@rule[-1].target='ACCEPT'

uci add firewall rule
uci set firewall.@rule[-1].name='Allow-DNS-IoT'
uci set firewall.@rule[-1].src='iot'
uci set firewall.@rule[-1].dest_port='53'
uci set firewall.@rule[-1].target='ACCEPT'

Please try again and let us know if this resolves the issue.

Note that after re-excute these commands, we will need to save the configuration again and restart the system .

9. Apply and Reboot
Finally, commit all changes and restart the router.
