-Basically the same as Ubuntu, except I tried with Debian Buster (10).  I updated to Debian Bullseye (11). When I updated to Bookwork (12) the update failed.  I then managed to corrupt the configuration files on the router.....

 Having used Ubuntu for the past many years I have grown use to netplan.  This is not native on Debian Buster, so needs to be installed: ''sudo apt install netplan.io''  it basically just seems to work.  Now I have gone back to preferring /etc/network/interfaces. Having used Ubuntu for the past many years I have grown use to netplan.  This is not native on Debian Buster, so needs to be installed: ''sudo apt install netplan.io''  it basically just seems to work.  Now I have gone back to preferring /etc/network/interfaces.

 Download the latest Ubuntu Server amd64 ISO file from the Ubuntu website. I setup the IPMI KVM to provide virtual storage to the Ubuntu ISO file and started up the Router. The Ubuntu software loads up of the ISO across the KVM virtual storage setup and can be then setup as normal.

 +======Manual Network Setup======
 +A lot of network equipment, such as routers and managed switches come with a default access IP address. In most cases this address does not align with the existing address space.  These device usually can not be directly plugged into an existing address space and function correctly if at all.  Normally an individual computer needs to have a manual address assigned that matches the default equipment address to allow allow access to the equipment to change the default access address to match that required.  
 +
 +There are many ways to manually change the computer IP to facilitate this, and this depends upon the operating system and software used by that computer.  A key point is that the assigned manual address and address mask must place the manual assigned address in the same address range as the equipment to be configured.  It may not be the same address.  Say the equipment default assigned address is 192.168.56.34, then the computer must have an address assigned in the space 192.168.56.x/24 (or mask 255.255.255.0), where x is between 2 - 254, except in this case 34, which is the default assigned to the equipment to be configured. 
 +  * ''ip a add 192.168.1.200/24 dev eth0''  to add an IP address to interface eth0
 +  * ''ip a del 192.168.1.200/24 dev eth0''  to add an IP address to interface eth0
 +
 +Once the computer network has been manually assigned and network reset check that the network address and mask have been correctly set.  If the assigned network mask is incorrect, that is in most cases not /24 (255.255.255.0), such as /32 (255.255.255.255) it is unlikely that the computer will be able to communicate to the equipment. In linux the following commands can be used to help:
 +  * ''%%ip a%%'' will return the computer interface IP address and mask.
 +  * ''%%nmap -sn 192.168.56.x/24%%'' should list the local computer address and the connected equipment address.  If only the computer then it is unlikely a connection to the remote device is available.
 +  * If accessing the equipment via a web browser, open a new page and ensure that the page is open directly not from cache.
