If running Charon-PAR in a cloud environment please consider that every cloud environment has specific networking characteristics that could conflict with interface configurations made by the user of the Charon-PAR host system. Please refer to the documentation provided by the cloud provider and the network-specific sections in the Getting Started Guide of your product to understand the networking behavior of your cloud instance before you change any interface settings (failing to do so may end with your cloud instance being permanently unreachable).

- If dedicating a host NIC to the emulator, the emulated system and the guest system must use the same MAC address and IP address on the interface that were assigned to the interface by the cloud provider. On the Linux level, the IP address must be removed from the interface.

The emulator can then communicate with the outside world via NAT, or with other other private networks via a routing configuration.
