Looking for assistance on ubiquiti Cloud Gateway Ultra (lemmy.world)

I wasn't sure if this was the best place to post this. A series of events happened and I recently changed up my home network.

One of the larger changes I made was to add a Unifi Cloud gateway gateway ultra.

Right away my biggest challenge is that it does not accurately list all of the client devices that it has given a DHCP lease to.

Has anyone else run into this issue?

I have some IP based security cameras that I have only been able to locate before by looking at my ISP's dhcp lease list and find the IP.

So right now I have cameras on my network and I have to brute force lookup the IP of them to figure out where they are.

A more minor annoyance is that the network topology map is wrong and that ubiquity switches are not being mapped.

It sounds like your ubiquity and your ISP router are on the same LAN segment, which is not a good config.

You should never have multiple DHCP servers configured unless you're intentionally split braining your vlan (only ever done that for HA purposes and using half of the pool on each). Im pretty sure you need to have your ISP connected to your cloud gateway, and all of your gear connected to the ubiquity. Your ISP router should only see your ubiquity, and that's likely a good part of the reason you can't see all the DHCP leases on your ubiquity gear.

Were I in your position, I'd probably disconnect everything and slowly reconnect stuff one piece at a time until you trip over what's causing your issue. I doubt this is the case, but you could also have another DHCP server running on something you forgot about causing issues. Seen that many times before when doing small business network overhauls.

I'll need to check for this. I have the ISP box plugged into the wan port of the router. It shouldn't also be handing out IP, but it very well may be.
