Virtual network configuration options | |
|---|---|
| Field | Description |
| Create for SSH VPN | If set to ON, a special virtual network will be created to be used as the basis for creating an SSH VPN tunnel as described in SSH VPN Operation- Connecting Charon Host and Guest to Customer Network. |
Binding interface | If set to ON, a physical interface can be selected from the Virtual bridge interface dropdown menu, on which the bridge is configured. The bridge is connected to the host system LAN. If set to OFF, a user-defined name can be entered in the Virtual bridge name field. This name will be used in naming the bridge and TAP interfaces instead of using the physical interface name. The bridge is internal to the host system. Always OFF if Create for SSH VPN is enabled. |
STP for bridge | Enable or disable the Spanning Tree Protocol on the virtual bridge. Always OFF if binding interface is set to ON or SSH VPN is enabled. |
Virtual bridge interface | Dropdown menu to select a physical interface that will provide an external network connection to the bridge. Inactive if the binding interface is disabled and if SSH VPN is enabled. |
Virtual bridge name | Used to set a user-defined bridge name if the binding interface is disabled. This name will be used in place of the physical interface name when creating the bridge and TAP interfaces. Inactive if the binding interface is enabled. Fixed name vpnX for SSH VPN configuration (X = 0, 1, ...). |
Number of virtual adapters | Specify how many virtual adapters are needed. |
IP settings | Specify the method used for addressing the interface used to connect the host to the external network. Options are Automatic (DHCP), Manual, and None. If the binding interface is disabled, manual configuration is mandatory (to assign a configuration to the host-internal bridge interface). |
IP address | If manual addressing is selected, the host IP address can be added in this field. The field is inactive if DHCP or None is selected. |
Netmask | If manual addressing is selected, the netmask for the host IP address can be added in this field. The field is inactive if DHCP or None is selected. |
Gateway | If manual addressing is selected, the default gateway for the host can be added in this field. The field is inactive if SSH VPN configuration, DHCP or None is selected.
|
DNS server 1 and DNS server 2 | If manual addressing is selected, you can add the IP address of one or two DNS name servers. Inactive if SSH VPN configuration is selected. |
Be careful not to select a default gateway not matching the AWS subnet structure. Doing so may cause you to permanently lose access to your instance....
