Multiple Whonix-Gateway ™
Multiple Whonix-Gateway ™ can be used alongside multiple Whonix-Workstation ™, but this has both advantages and disadvantages. One security benefit is the isolation of separate Whonix-Gateway ™ VM instances. In the event that one Whonix-Gateway ™ is compromised, it is not certain the other(s) will be similarly compromised. On the downside, newly cloned Whonix-Gateway ™(s) will end up with a different set of Tor entry guards unless precautions are taken.  
In this configuration ISPs are probably capable of detecting that two different Tor data folders are in use, but this is not necessarily an anonymity threat. Similarly, if multiple Tor Browsers are used with distinct Whonix-Gateway ™, then a different set of Tor entry guards will be used as well (unless by chance the same Tor guards are chosen for different Whonix-Gateway ™).
When multiple Whonix-Gateway ™ are run in parallel, the risks explained in the Multiple Whonix-Workstation ™: Safety Precautions section equally apply.
In this configuration, Whonix-Workstation ™ will not be able to communicate with one another. This is recommended to keep different Tor activity profiles completely separate. To run multiple Whonix-Gateway ™ it is necessary to clone existing VMs; the steps below assume an existing Whonix ™ install.
In VirtualBox Manager, change the name of the internal network is required for both, Whonix-Gateway ™ and Whonix-Workstation ™
1. Know the Whonix ™ default internal network name.
2. Pick an alternative internal network name.
For the second, third or nth multiple Whonix-Gateway ™ another internal network name is required. Can be any name. Just make sure to not re-use it in other Whonix-Gateway ™'s which should be isolated from this one. The following example will use
Whonix2. But it could also be something completely different such as
3. Change Whonix-Gateway ™ internal network name.
VirtualBox → Whonix-Gateway ™ →
Adapter 2 →
Name: → change
Whonix to something else such as
4. Change Whonix-Workstation ™ internal network name.
VirtualBox → Whonix-Workstation ™ →
Adapter 1 →
Name: → change
Whonix to the same internal network name as above →
The only requirement is that the newly created
sys-whonix is based on the
whonix-gw-15 TemplateVM and has a distinctive VM name, so it is not confused with other VMs.
