Using ISY994i without UPnP

[Tim E]

Is it possible to use my computer to set up the ISY994i controller without UPnP? I have no plans to communicate with the ISY994i remotely via internet. I only need to set it up while I am at home, with my computer and the ISY994i connected to the same local network.

Yes. its that way by default. Most routers have UPnP turned off.

Thank you for the prompt reply.

Since I am considering buying the ISY994i, I just want to be sure I understand first:

My planned configuration is:

Operating system: Windows 10
Router: U-verse 5268AC router/gateway (does not allow UPnP)
Computer connection: Directly to router by Ethernet cable.
ISY994i connection: Directly to router by Ethernet cable.
PLM connection: To ISY994i via serial cable.

With the above connections, should I be able to access the GUI using my browser, even though UPnP is not enabled?

Hi Tim and welcome to the UDI Forums!

Yes. I've had my 994I for 5 years and have never used UPNP. Its a "left over" option from years ago. I give the ISY a static DHCP entry IP address from my router's reserved address function and have the ISY set for DHCP. I don't know that particular router, but the ISY will behave like other internet appliances

UPnP has nothing to do with one device accessing any other device inside your own LAN, ISY included.  If you want to access ISY from outside your LAN, subscribe to Universal Device's portal.  It is cheap, secure, and includes connectivity for Google Home, Amazon Alexa,  and IFTTT (webhooks).  In comparison, UPnP opens inbound connections from the internet, the portal on the other hand opens an outbound connection.  This is totally different and at the very top of secure ways to do things.  The only way you can be hacked on an outbound connection is if the thing you connect to is compromised.  Like going to an evil website or one that has been hacked.

My LAN does not function without uPNP.

You will hear a lot of rumours about it, but most routers require it to enable devices to find each other on your LAN system.

However, there are sometimes options in routers to allow uPNP services to pass through to the outside world and that has been deemed to be a dangerous thing for security against hacking.

I suggest googling uPNP. Wikipedia has a fairly good description of its operation and security details.

I have disabled uPNP in routers several times and found my systems just won't function without it anymore. Without it, you will have to operate your devices like the 1990s by specifying absolute network addresses for every connection.

I don't have UPnP on my router and everything finds everything.  Either way, worse case scenario is that you have to enter the ip address of ISY into the ISY finder instead of it just finding it.

UPnP has never been enabled on my Ubiquity network nor any router I've ever owned without any issue. As long as devices are on my same network I've never had a single instance with any hardware giving me a hard time.

Exactly where I am.  I just looked up if the ubiquiti usg even has upnp and discovered it does, but it would seem you can only enable it via a command line entry.  As far as I can tell, they don't have it in the gui, I assume because they consider it something you shouldn't do. It would seem, from a few searches, that upnp conversations often center around peer-to-peer gamers.  Something I don't do.
