Virtual Network Hub is an easy way to connect computers and devices into a single or several networks. It has a visual appearance of a hardware network hub and creates a familiar environment for users to apply their hardware settings onto this virtual device. The Drag-n-Drop interface allows to visually assemble a hub and fine tune its settings for various networking tasks. Virtual Network Hub brings a number of now popular features:
Virtual Network Hub has two main software components: the service and the user interface (UI). The service can work without the UI. It performs monitoring and automatic reconfiguration of the underlying network driver. The UI manages configuration of the service and requires the service to be running.
UI shows available adapters on the left side and configurable networking hubs on the right side. Each hub represents an isolated network segment. There are could be more than one hub added to the hub list. The order of hubs can be changed by dragging them or by clicking the hub ordering toolbar buttons . The order of slots within a hub can also be changed by dragging them. However, the order does not make any difference from the network routing perspective.
To construct a hub, either select the existing hub with empty slot or create a new hub with . Then, drag a network adapter from the left list onto an empty hub slot or a space behind the last assigned slot. This would assign the adapter to the existing slot or create a new slot and assign the adapter to that new slot. Alternatively, a network adapter can be assigned to a new slot of the selected hub by clicking button of the network adapter.
All changes to hubs are applied automatically with a short delay as configured within UI settings .
A network adapter can be assigned only to a single hub slot. Each slot has its own configurable settings that define functionality of the slot.
Default gateway - the slot acts as a client to another (uplink) router. The slot requests a dynamic IP address. Default gateway slot is highlighted within the hub with a different color and labeled with the icon . Packets are sent via default gateway when the destination IP is determined to be on a different network according to the subnet mask of hub's DHCP server.
Internal DHCP server issues IP addresses - the hub's DHCP server provides dynamic IP addresses to device connected to the slot. The range of IP addresses and other DHCP parameters can be configured within hub settings .
Smart - the slot receives only the traffic intended for the device connected to it. All other traffic that is passing between other slots of the hub is filtered out.
Unfiltered - the slot receives all traffic without filtering. The traffic passing between other hub slots is visible to the device connected to this slot. This setting is often used for network monitoring and it turns the slot into a slot of a network switch.
Network adapters on the computer running Virtual Network Hub can be used not only by Virtual Network Hub itself, but also by other programs.
Exclusive - the network adapter associated with the slot is used exclusively by the Virtual Network Hub. Other programs do have access to the network adapter, but all their traffic passing through the associated network adapter is silently discarded.
Non-exclusive - the network adapter associated with the slot can be used by all programs on the computer. All traffic from other programs passing though this slot is routed according to the hub settings.
When a slot is designated as a default gateway, it acquires its IP address dynamically from the uplink router. The acquired IP can be viewed on the DHCP Client information tab.
A hub slot with an assigned wireless network adapter can act as a WiFi HotSpot. Only a single HotSpot is supported amongst all running hubs. Not every wireless network card supports WiFi HotSpot functionality. Only the network cards with SoftAP mode explicitly stated in their specification support that.
To enable WiFi HotSpot functionality check the appropriate box and provide the settings for the HotSpot. The WiFi HotSpot slot is highlighted with a golden color. All additional parameters including DHCP server and slot exclusivity are set automatically. The 'Connected peers' list is automatically refreshed to show MAC addresses of the connected wireless devices. The device is considered to be connected after it provides the correct password and is fully ready to communicate.
Hub settings include configuration shared by all hub slots.
Each hub has a single DHCP server instance. Hub's DHCP server provides IP addresses for all hub slots that are configured within their settings to provide dynamic IP addreses by internal DHCP server.
Subnet mask - allows hub to determine which IP addresses are outside of the current sub-network and when to route packets onto default gateway slot.
Starting and Ending IP addresses - they define the range of dynamic IP addresses issued to clients. This range should have at least 2(two) IP addresses. The highest IP address is taken by DHCP server itself and is not issued to connected devices.
Default lease duration - the default value is 24hr. The leases of this duration are issued when connected clients do not request any specific lease duration. The leases are periodically extended by connected devices upon their requests. This value should not be too large to avoid running out of IP address space when disconnecting devices do not explicitly release their IPs.
Max lease duration - it is the maximum lease duration issued by DHCP server when a DHCP client requests too long lease duration.
Domain name - it is a unique domain name will be provided to DHCP clients. It is a textual name which the clients would use for resolving their own name and names of neighboring devices when no other information is available.
DNS servers - additional DNS servers to be provided to DHCP client. When a hub has a default gateway, the DNS servers from the default gateway are automatically provided to DHCP clients as the top DNS servers. Whenever a hub does not have a default gateway, the DNS servers from the settings list are the only DNS servers provided to DHCP clients.
Gateways - default gateways to be provided to DHCP clients. Whenever a hub has a default gateway slot, its IP is automatically provided to all DHCP clients as a top default gateway. However, when a hub does not have a default gateway slot, the Gateways from the settings list are the only gateways provided to DHCP clients.
DHCP server statistics can be seen on the DHCP Server Stats tab.
A hub slot can be designated as a default gateway. Such default gateway functionality includes a DHCP Client that obtains IP address dynamically from the uplink router. DHCP Client settings define the identification the default gateway slot (DHCP Client) will provide to the uplink router (or another DHCP server) to obtain the IP address.
Besides settings for hubs and for slots, Virtual Network Hub has program-wide settings.
'Default DHCP Server' settings simplify configuration of DHCP servers for new hubs. These settings are copied into new hubs upon their creation.
Various user interface settings can be adjusted to user preferences.
The user interface can be configured to minimize to the system tray area when attempted to close.
The status of each network adapter can be retrieved by clicking icon on the network adapter.
