OC200 Hardware controller does not see the router ER7206 as a gateway even
My OC200 Hardware controller does not see the router ER7206 as a gateway , it is connected to the controller but is not seen as a gateway , my network is 10.1.5.1-10.1.5.255 mask 255.255.255.0 GW 10.1.5.251 -- ER7206 , is working but no gateway statistics and when I activated the UPNP service it has an exclamation sign and says gateway required !!!
What should be the problem ?
How to instruct omada controler OC200 to see the router ER7206 as a gateway ?
I set the lan to 10.1.5.251/24 in settings LAN of the controller
I set the ip of the OC200 controller static as 10.1.5.18 netmask 255.255.255.0 gw 10.1.5.251 dns 10.1.5.251 dns secondary 8.8.8.8
Thank You in advance
