My router is setup as a wireless access point and I want it to provide dhcp server so my primary router only handles NAT.
Is this possible ?
My AP is MR3020 and on the TP-Link firmware this was possible.
The only problem I see now is that there is nowhere to define the gateway IP address in the dhcp server settings of the MR3020 in dd-wrt.
Thank you in advance.

Thank you eibgrad!
After adding the gateway ip to the lan side, the dhcp server is still giving the AP ip address as the router ip but the clients are getting internet!
So I think this is DNSMasq working.

After adding this option the dhcp server is giving the addresses correctly!
Thank you eibgrad, much appreciated!
What does the 3 after br0 signify?
