WLC problems

Hi! I have a network consisting of 1 router as a dhcp server which is connected to the main switch (SW-MAIN) , this switch has 1 controller connected and is also connected with multiple PoE switches with APs on them. The router has an ip of 10.10.10.1/22 and the managment ip is 10.10.11.240 on vlan 1 with primary dhcp ip 10.10.10.1(the router). The ports between switches, switch-controller and switch router are all Trunk, the controller cant ping the router and cant get IP's from it. Is there any extra configuration that should be done on the router to forward dhcp? Or is the problem somewhere else?controller, LAN Switching

Hi, I'm a bit confused. Is it correct, that the main router IP and the management IP are in the same network (10.10.10.0/22)?
However, if you want to use the router as a dhcp relay, you have to use the command ip helper-address within the interface configuration.
