Select the host attached Ethernet device to be connected to the virtual device. This field is a drop-down list of all the network adapters available on the host system. Important points:

• On a Charon-SSP AWS cloud-based 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 AWSthe cloud provider.

• 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 AWScloud-specific products. 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.

 This option can be useful in cases where licensing is tied to a network adapter MAC address. It is required if a dedicated NIC is used on the Charon-SSP AWS cloud-based instance.
