with the new version I can only create one portal per site :-(

I really recommend to RTFM before upgrading.

From the Omada SDN Controller Upgrade Guide:

Why had this been changed?

Probably because:

   - SDN Controller has major changes regarding features to be configured and adjusted features (see the Upgrade Guide),

   - the portal will now work also for wired devices such as those connected to EAP-WALL ports & switches and

   - the capture mechanism for the portal had to be changed for the latter function?

Just guessing, maybe it has those and/or other reasons.

Anyway, this is not the only major change making SDN controller a completely new product in my opinion, so I strongly recommend to RTFM.

HKBlizzard, can be seen from different points of view:

In older versions of Omada Controller it was not possible to use a portal for wired devices (wired to an Ethernet port of an EAP-WALL or a switch). This was a real drawback. If I understand the manual correctly, such portal redirects of guests using wired devices will now become possible with SDN Controller.

As I wrote, I'm guessing only. In our own Captive Portal software we have this restriction of one portal per site since ever, but we always could redirect guests to a portal even if they used a cable connection to an EAP-WALL using their Ethernet port(s) or a connection to a switch. In our software this restriction of one portal per site has technical reasons.

For some customers this might be a drawback, for others it's a long-awaited improvement.
