Hi all,

 

I am constantly seeing an error message on my UDMPro - 

 

Multiple devices are using the same IP address: 192.168.50.70. Please check each device's configuration to ensure none are communicating with a rogue DHCP server.

 

 

This is my current Unraid setup - 

• 3 x NICs setup as a Bond0 (Active-Backup configuration)
  • All setup as trunk port - native VLAN 50 - IP: 192.168.50.10 (static)
• Under this bond0, I have multiple VLANs setup for each of my networks
  • VLAN 10 - Main - IP: 192.168.10.206 (DHCP)
  • VLAN 20 - IoT - IP: 192.168.20.206 (DHCP)
  • VLAN 30 - Camera - IP: 192.168.30.206 (DHCP)
• Docker containers running under different networks, some using bridge mode, some using bond0 and some with custom internal network
• VMs using vhost0

 

Why do I see duplicate IPs for 192.168.10.205 but not for any other network?

 

Also, can anyone tell me the different between the different gateways configured on the networking within Unraid - 

• docker0
• br-<random num>
• vhost0
• bond0
• virbr0

 

 

Also, which gateway is used for accessing various things on Unraid externally?

• Unraid web interface
• Docker containers
• VMs

 

thanks so much!

Rory

I have the same issue.

 

No clue where or WHAT is using the same IP.

I wish there was a script, plugin,.. that said, THIS exactly THIS thing is causing you problems, so change its IP or SOMETHING !!!!

Mine seems to do this because of Settings -> Docker -> network "macvlan"
