NAT

To access the NAT Public IP Address field:
1. Navigate to

>
NAT
section.
IP Address This is either a static or a DHCP-enabled IPv4 address. If IPv6 is
turned on for this segment of the network, this will be an auto-
generated global IPv6 address. If using IPv6, use the IPV6
Address field below. Note: Although the IPv6 address is displayed,
it cannot be used to manage the appliance as yet.
Subnet Mask Subnet mask for the DME address.
Gateway IP Address Gateway IP Address for communicating across distinct network
segments.
Maximum Transmission
Unit Size Range 500–1500 (default = 1500). The MTU is used for all
network traffic from the DME and defines the largest network
packet size that will be transmitted. A higher MTU brings higher
bandwidth efficiency and Vbrick recommends using the default.
However you may wish to reduce MTU size to meet the
requirements of some networks with VPN or other security
tunnels that cannot tolerate 1500 byte packets.
Configured Interface
Speed / Duplex Default = Auto Detect. Use Auto Detect or manually set the bit
rate and duplex setting for network devices that do not support
auto negotiation. With Auto Detect the DME will automatically
adjust its duplex setting and speed to match the switch or hub to
which it is attached.
Detected Interface
Speed / Duplex Read only. Displays the current connection speed and duplex
setting.
MAC Address The Media Access Control address is a unique identifier assigned
to the DME for network communications.
IPV6 Address Optional. Enter an IPv6 address.
IPV4 Network Interface
2-4 The DME will auto detect the number of NIC cards installed. If
more than one NIC is installed, you can use the additional card(s)
to increase bandwidth and throughput.
• Disabled – Default. You can disable the NIC if, for example,
you have bandwidth constraints imposed by your network or
service provider.
• Load Share Enabled – The NIC will load balance the resources
used by output streams.
