| -        | When the user connects with Telnet to the VNF from CloudGuard Edge and then presses the ENTER key, it will be regarded as a "double" ENTER (this will happen every time the user presses the ENTER key). |
| -        | Changes to the Security VNF while deployed in the VCO will result in a redeployment of the VNF.                                                                                                          |
| SMB-9382 | All created VNFs use the same MAC address.                                                                                                                                                               |
| -        | VNF configuration cannot be changed.                                                                                                                                                                     |
| SMB-9288 | In rare scenarios, policy installation of CloudGuard Edge fails when using 1 GB RAM.                                                                                                                     |
|          | The following features are not supported: VTI, Email Security and Anti-Spam.                                                                                                                             |
|          | The following features are not supported in Layer 2 deployments only: Dynamic Routing, NAT.                                                                                                              |
