Hello. @Fae 

I'm trying to figure how to manage two controller in the same Lan that act as offsite controllers.

Actually I'm stock with old remote devices linked with Omada controller 3.2.6 and another new controller V5 that can only manage Onsite devices.

Is there a way to use ports with url inform to get link with remote devices to the SDN controller in the same Offsite Lan ?.

does the play with inform url type :   omada://offsite.domain.url?dPort=29821&mPort=443  where the 29821 port forward to 29810 IP LAN SDN controller will work ?

TKS for advise.
