57 Physical world

This chapter is my notes on various hardware configurations that I took in the physical world.  Setups, screenshot, notes, nothing really organized, just taking it off of paper notes for others if they want to look at it.

Using the above to connect PC’s to each other.

Must have admin rights to the host PC to make the following changes:

• Navigate to the Networks connections settings in Windows 11 settings
  
• Rename the connection to something easily recognizable; it makes things easier in GNS3
• NOTE – Sometimes I had to connect the RJ cable for USB settings to appear and be changed.  I didn’t find a common denominator, but I didn’t look very hard either.  If it didn’t show or I couldn’t do anything, I just plugged a cable in so I could keep working.
• Right-click on the adapter and select properties
  
• Turn OFF (no checkmark) for IPv4 and IPv6
  
• Press ok
• NOTE: I always disable then enable the network connection.  I don’t know if this is necessary, it was just habit. 
• 

Start the GNS3 environment

• Open a new project
• Drag a cloud to the environment
  • When asked how to run the cloud, select the PHYSICAL MACHINE (whatever it is called) and not the GNS3VM.
    
  • Double-click on the cloud name and rename it to something meaningful.  Here I called it BLUE_RJ_USB
    
  • Right click on the cloud and select configure
    
  • Here you will select the PHYSICAL interface that the virtual cloud will connect too.
    
  • To avoid confusion, I delete all interfaces by clicking on them and clicking Delete
  • Then select the drop down and look for the interface name we gave the physical interface on the Windows Physical host machine
    • You might have to click the “Show Special Ethernet Interfaces” box at the bottom
    • Once you highlight it in the drop down box click on add
    • 
  • Select apply –> ok
  • You can then add a VPCS like normal and connect it to the cloud on that interface. It will act as a passthrough interface across the physical wire.

Repeat on another physical machine
