i've created 3 vlans on the controller , vlan 15 which is the controller switch ip "APs will use this ip for conversion process" also i've created another 2 vlans , vlans 5 and 10 , these 2 vlas will carry the traffic of 2 ssid , they are trunked to a switch , and the switch uplink the traffic of these 2 vlans to 2 separate intefaces of a fortigate firewall , these 2 interfaces of the firewall acts as a dhcp server for clients . the issue here is the controller can reach the internet from only one vlan interface at a time , the vlan inteface which has a default gateway with the least cost "the gateway here is the lan interface of the fortigate firewall " . i tried to make on the controller one vlan with static ip and other vlan takes ip dynamically from the firewall , but also faced the same problem . could you please tell me how to make the controller reach the internet form vlans so the clients on both SSID can reach the internet ?
