To create a virtual network, click the Create Virtual Network button. For further details on creating, changing and removing a virtual network, see the section Host System Network Configuration. Do not use Charon-SSP Virtual Networks in combination with VMware ESXi vSwitch virtual network adapters. The vSwitch does not implement the STP protocol. This could lead to a layer‑2 loop disrupting normal network operationOnly internal bridges (without binding interface) can be used with Charon-SSP AWS.
To modify an existing virtual Ethernet adapter, select it from the list of configured devices and click on Edit (the edit button becomes visible once an interface has been selected).
To remove an existing virtual Ethernet adapter, select the adapter from the list of configured devices and click the Remove button (the remove button becomes visible once an interface has been selected).
To add a new virtual Ethernet adapter, click the Add button.

After selecting to add or to edit an adapter, a window similar to the one below will open:

The following parameters can be configured:
...
On a Charon-SSP AWS host, you can either use an internal bridge to create TAP interfaces that will then be used in the emulator configuration, or you can use a dedicated NIC. If a dedicated NIC is used,
the MAC address of the emulated interface must be set to the MAC address of the NIC connected to the Charon host, and
the IP address of the guest system must be set to the private IP address allocated to the NIC by AWS.
It is permitted to assign the localhost interface (lo) to an emulated device (if only a dummy device is required in the guest).
- Some options are configurable, but will not work with Charon-SSP AWS. They are listed here only for completeness:
Using the same physical device for multiple emulated Ethernet devices of the same instance.
Sharing a NIC between emulator and host (i.e., both have their own IP address on the same interface).
Assigning the same physical interface to more than one Charon-SSP instance.
