Ver. 6.11.5 2022-11-20 - unRAID changes IP

[JGNiDK]

I have a problem with my Unifi, which apparently is because my unRAID is acting very weird. It steals my Unifi Security Gateways IP 10.0.0.1.
Any ideas what to do is highly appreaciated.

Check your docker containers running on a custom network.

To avoid IP overlap, you need to set a DHCP range for the custom network which assigns addresses outside to what your router is assigning.

I might misunderstand something here, but then I hopefully learn something. 
But e.g my nextcloud here, is using same IP as unRAID. So am I doing something wrong?

No, in this case you use a custom bridge network which does network address translation.

The container uses an address in the 172.20.0.x network but communicates to the outside world using address 10.0.0.211 (this is expected)

So what should I look for?

Do you see 10.0.0.1 assigned to any interface in unraid network, docker or VM settings? 

 

What is Vader, is it the name of your unraid server? Have you tried finding what the MAC address listed next to Vader in your first screenshot corresponds to? 

 

What acts as your dhcp server? Is that unifi? Check the configured dhcp ip allocation range as suggested 

 

Does the USG come back online if you unplug unraid from the network? 

 

Docker using unraid IP is OK, your problem is not that IP. Need to find out what 10.0.0.1 is assigned to

Nope. Nowhere.

Vader is my unRAID-server yes. The MAC is eth0

My uSG. Which is weird when it's offline. But never the less. 
All my Docker containers use .211 and my HA in VM uses .245. So it should be oki?

I turned off my unRAID for 30 minutes yesterday. Then I'm also turning off my Unifi Cloud controller. So a little difficult to be 100% sure. But when I turned on my unRAID again, it was offline.

I totally agree!!

 

[JGNiDK]

Right now.....

 

[JGNiDK]

Oki note something strange happened. I changed unRAIDs IP to DHCP, to see if it would take 10.0.0.211. Now all net is gone!! What's going on I wonder?? 

And how too change it back???

 

[JGNiDK]

My Docker and network settings now

[JGNiDK]

Something is really strange now

Where is your unifi controller running? I have a feeling something is wrong with your unifi network. Taking unraid off the network, does the rest of your network work well? Can you ping the gateway at that point. If not, you should fix that first

unRAID. But everything is dead right now. So I'm very unpopular right now

The issue seems to have started with Tailscale and change of LAN network. I’ll take it from here, but will return in a new thread if I can’t solve the issues I still have with the network.
