Creating a Virtual Switch in Advanced Mode

  1. Go to Control Panel > Network & File Services > Network & Virtual Switch.

    The Network & Virtual Switch window opens.

  2. Go to Network > Virtual Switch.
  3. Click Add.

    The Create a Virtual Switch window opens.

  4. Select Advanced Mode.
  5. Select one or more adapters.
  6. Optional: Select Enable the Spanning Tree Protocol.
    Tip:

  7. Click Next.
  8. Configure the virtual switch IP address.

    Address Type

    Description

    DHCP Client

    Assigns a dynamic IP address to the virtual switch.

    Static IP

    Assigns a static IP address to the virtual switch.

    Tip:

    Examine your network setup for guidance on how to best configure these settings.

    Do not assign IP Addresses

    Does not assign an IP address to the virtual switch after creation.

    Tip:

    This setting should be used when creating a virtual switch for special purposes, such as when building an external or isolated network.

  9. Click Next.
  10. Configure the virtual switch services.
    1. Enable the NAT service.
      Important:
      • The virtual switch must be configured with a static IP address. The IP address cannot be within the subnet of an interface that is currently in use.

      • The IP address of the virtual switch cannot be in a reserved range that doesn't support forwarding:

        • 127.xxx.xxx.xxx

        • 169.254.xxx.xxx

        • 192.0.2.xxx

        • 198.51.100.xxx

        • 203.0.113.xxx

    2. Optional: Enable the DHCP Server.
      Important:
      • The virtual switch must be configured with a static IP address. The IP address cannot be within the subnet of an interface that is currently in use.

      • To avoid IP address conflicts, do not enable DHCP server if there is another DHCP server running on the local network.

      Setting

      Description

      Start IP Address

      Specify the starting IP address in a range allocated to DHCP clients.

      End IP Address

      Specify the ending IP addresses in a range allocated to DHCP clients.

      Subnet Mask

      Specify the subnet mask used to subdivide your IP address.

      Lease Time

      Specify the length of time that an IP address is reserved for a DHCP client. The IP address is made available to other clients when the lease expires.

      Default Gateway

      Specify the IP address of the default gateway for the DHCP server.

      Primary DNS Server

      Specify a DNS server for the DHCP server.

      Secondary DNS Server

      Specify a secondary DNS server for the DHCP server.

      Important:

      QNAP recommends specifying at least one DNS server to allow URL lookups.

      WINS Server

      Specify the WINS server IP address.

      Tip:

      Windows Internet Naming Service (WINS ) converts computer names (NetBIOS names) to IP addresses, allowing Windows computers on a network to easily find and communicate with each other.

      DNS Suffix

      Specify the DNS suffix.

      Tip:

      The DNS suffix is used for resolving unqualified or incomplete host names.

      TFTP Server

      Specify the public IP address for the TFTP server.

      Tip:

      QTS supports both PXE and remote booting of devices

      Boot File

      Specify location and file name of the TFTP server boot file.

      Tip:

      QTS supports both PXE and remote booting of devices

  11. Click Next.
  12. Configure the virtual switch IPv6 address.

    Setting

    Description

    Disable

    Do not assign an IPv6 address.

    IPv6 Auto-Configuration (Stateful)

    The adapter automatically acquires an IPv6 address and DNS settings from the DHCPv6-enabled server.

    Important:

    This option requires an available DHCPv6-enabled server on the network.

    IPv6 Auto-Configuration (Stateless)

    The adapter automatically acquires an IPv6 address and DNS settings from the router.

    Important:

    This option requires an available IPv6 RA(router advertisement)-enabled router on the network.

    Use static IP address

    Manually assign a static IP address. You must specify the following information:

    • Fixed IP Address

    • Prefix length

      Tip:

      Obtain the prefix length information from your network administrator.

    • Default Gateway

  13. Click Next.
  14. Configure the DNS settings.

    Setting

    Description

    Obtain DNS server address automatically

    Automatically obtain the DNS server address using DHCP.

    Use the following DNS server address

    Manually assign the IP address for the primary and secondary DNS servers.

    Important:

    QNAP recommends specifying at least one DNS server to allow URL lookups.

  15. Click Next.
  16. Confirm the virtual switch settings.
