I tried created one more DHCP server(server2) with different SSID on my RB951g, Could you please help to advise why it's always red? my configuration file as below

BTW, I try to change wlan2 as bridge2, but still red.

wlan2 doesn't have an IP address.

wlan2 is already a member of bridge2.
Bind the server to bridge2 and it will work.
Additionally, bridge2 doesn't have an IP address...
What's your intention to have the same DHCP pool in two different bridges?

Got it, Thanks for your information.
