I run two Whonix-Workstations with the same IP address at a time and did not change the IP address manually as described in the documentation (Multiple_Whonix-Workstation). The MAC-address changed automatically after cloning the Workstation in VirtualBox. I assume this could be adjusted in the documentation as there are no further steps necessary.
Everything worked as desired. Could you tell me about the specific risks which occur when running two Workstations with the same IP address?
That’s interesting. I experimented with this now, and the MAC address does change automatically for a clone, which I find a bit surprising. What else gets changed?
Connectivity might be unstable.
Using the same IP address would worsen stream isolation.
Tor’s IsolateClientAddr Stream Isolation feature requires different IP addresses.
VirtualBox GUI points that out.
Get machine readable output of VM settings of VM 1. Can be done with the following command.
VBoxManage showvminfo vm-name
Note: Replace vm-name with the actual name of the VM.
Store its output in a file.
Get machine readable output of VM settings of VM 2.
Store its output in a different file.
Compare the two files using File Comparison Tools.
Have not check yet for other changes. Using VirtualBox 7.0
Clicked on Clone (Whonix-Workstation).
Then did not change the default which is:
And after the cloning process under settings-network of the cloned Whonix-Workstation I see another MAC address.
