UDM PRO Unifi with Internet Box 3 10gb

  • I switched from UPC to Swisscom with fiber optic. I use a Unifi Dream Machine Pro as a router behind the IB3. This was easy with UPC because it has bridge mode.

    Now to today’s situation. The UDMPro has a LAN network of 192.168.0.1. With the Anschluss of the IB3 I then get a WAN IP 192.168.1.3. So far so good. DMZ is set to 192.168.1.3. But here I have the problem that the UDMPro does not appear as a device in the overview on the IB3. This means it appears briefly as a PC and then disappears again. In this constellation I can configure the UDMPro via the cloud. But the rest of the internet doesn’t work. Can someone tell me what exactly I need to set on the UDMPro in the WAN? I’ve read something about DHCP Option 60? Is something like that needed? What about DNS servers? Do I have to enter anything else there? Thank you for your help.

      You’ve probably noticed that the way to integrate a UDMpro is not quite the same as how to integrate a USG (did you get the link you asked for?). The biggest “problem” is actually that the IB3 (like all Swisscom routers) uses the 192.168.1.0/24 network and the fallback IP of the UDMpro and the USG is 192.168.1.1 by default. You have to change this first (either on the Unifi device or on the IB3).

      You have already solved this problem, your UDMpro has the 192.168.0.1; You probably changed that yourself when you first started using the UDMpro 😉

      Where exactly is the UDMpro not displayed now? Here in this overview?

      Then I would simply restart the IB3 again, then the UDMpro and then wait 1 hour until everything settles down again. Unfortunately, the IB3 is not always 100% accurate.

      - What firmware are you using? Do you have the current version, 12.00.52?

      - On the IB3 you have the UDMpro in the DMZ. But haven’t you set up a static route to the UDMpro?

      - At UDMpro, what software version do you have there? Beta, release candidate or official? -> This has been working for me with Beta for a long time.

      - My WAN port is configured like this:

      04-08-_2021_17-16-54.jpg

      - and the LAN part like this:

      04-08-_2021_17-19-44.jpg

      I haven’t configured anything else on the UDMpro and so I can access the Internet with my clients from the Unifi network.

      The only difference to you: my UDMpro uses the network 192.168.3.0/24, the gateway is therefore 192.168.3.1, and my UDMpro is not directly connected to a LAN port on the IB3, but there is also a switch (Unifi etc. 16-PoE) in between. But none of that should matter.

    @Hulaulu12

    The IB3 itself is configured normally, i.e. including an active DHCP server?

    If you connect a PC directly to the IB3’s LAN, does everything work normally including internet connection, display on the device list, etc.?

    Yes, exactly IB3 configured normally with DHCP. With the IB3 I also see my PC which is connected via WLAN. Unfortunately, as I said, I don’t see the UDMPRO, it only says that something is connected to port 1, for example, but not what.

    Show original language (German)

    Yes, exactly, that works too. The UDM gets the WAN IP address from the IB3 = 192.168.1.3, the IB3 itself has the IP 192.168.1.1.

    The UDM LAN network is 192.168.0.1

    Show original language (German)

    Have you plugged the LAN cable into another LAN port on the IB3, or actually tried out the LAN port on the IB3 with a PC, because your configuration should actually work as you have defined it without any further settings.

    Of course Walter’s link doesn’t help because it’s a different configuration.

    In your case, the ib router remains and your UDM lags behind.

    You can set the WAN of the UDM with IPv4 to dynamic and set up the DMZ on it after obtaining the IP from the Internet Box. The best way is to set the lease statically on the IB.

    Or you can set the UDM’s WAN to static. In the default IP network config of the IB, for example.

    WAN 192.168.1.10/24

    Gateway 192.168.1.1

    DNS: Any

    Then set up the DMZ and this IP of the UDM again.

    For IPv6 you can theoretically set the WAN to IPv6 PD with the prefix /60.

    But I don’t know whether this works in practice.

    The iB should now get native IPv6 with a /56 prefix. This means that if everything was programmed correctly, a sub delegation with /60 would be possible.

    The LAN network of the UDM is 192.168.0.1 so the device is not in the IP range 192.168.1.x of the IB3?

    This is about a router cascade and the networks of the two routers must of course be different.

    Only the downstream router itself should be part of the IB3 network with its WAN IP.

    Thank you for the help, I don’t really know what I did wrong, but everything works now. What’s strange is that the UDMPro is recognized as PC53 in the IB3?

    The UDMPro has version 1.10.0.3686 and the IB3 the 12.00.52/12.00.62/01699

    Now I have the pleasure of bringing the Swisscome TV to the upper floor. I hope this works better

    Nice, it works now.

    There’s nothing funny about the name, it’s simply an inadequacy. Whether from the IB3 or the UDMpro? No idea, but it basically doesn’t play a role in the function. I also renamed my UDM in the IB3 menu so that it says “UDMpro” (by the way, renaming the devices in the IB3 GUI is probably one of the most frequently used functions 😉 )

    Do you want to operate the TV-Box in the Unifi network?

    Then read this thread about it. The performance for Swisscom TV is better if it stays directly in the IB3 network:

    a year later

    I have UDMPro with Network 7.2.92.

    I only connected the 10G port with one IP to the WAN link (WAN2, Ethernet port 10). WAN link everything on automatically. Unfortunately, the connection does not, or not always, survive a power interruption.

    I’ve had trouble getting the link rebuilt a few times.

    There was a power outage today and the connection was lost.

    In the UDMPro log I found indications of problems with the SFP+ 10GB adapter from Unifi. Then I thought that maybe a new firmware was the problem. After a lot of back and forth, I replaced the media adapter. Unfortunately without success. (In the console you can see no green light and no IP on the internet connection)

    Then I hung an aggregate switch in front of the WAN link and connected it with a fixed optical 10GB cable.

    No success. (But the green light is on in the console, but still no IP)

    Then connected a notebook direct with a 10GB card to the cable of the Swisscom router. It was discovered that the lease had somehow not been released correctly. After plugging and unplugging the cable, I received the free public IP address. So go back and plug the cable into the aggregate switch. No connection.

    Then set the WAN link from Auto to Manual in the console and the IP to Static and now everything works again.

    Does anyone have an idea where to start looking?

    Are there any problems with the Unifi 10GB SFP+ media adapter for RJ45?

    Or is there a lease problem with the IB3?
    How do I get a log on the IB3 to find out if I have a problem on the site?

    The IB3 does not have a 10 Gbit LAN port, but rather 4 Gbit LAN ports and an additional 2.5 Gbit LAN port.

    The first thing to do is to clarify which Swisscom router you are actually using.

    If it is actually a Swisscom Internet box, the question about the logs is very easy to answer:

    There are no logs visible to the user.
