I use MP70 as DHCP server on my internal wireless network. The normal delivered address is 192.168.13.x, but sometimes the units receives a 10.2.1.x address which means they are unable to communicate with the other units connected to this MP70. Where does the 10.2.1.x address come from? I don’t have any other DHCP servers on the network, and the connection is lost to both subnets if I turn off the MP70.  
Only the 192.168.13 network is visible under the DHCP settings.

Hi @thp,  
10.2.1.X usually is assigned for VPN connection. Please check if VPN is enabled on MP70 as screenshot

VPN was not enabled. I reset the unit to factory settings and uploaded the same template again, and I have not seen the problem since.
