Description
Set the gateway address for this network port. If
the Set as Default option is selected, the device
packet will be forwarded through this gateway by
default when there is no matched static route. In
this case, a default route is displayed in the list of
the Router page.
The Network Address Translation (NAT) function
enables you to translate a private network IP
address into a public network IP address before
transmission. To enable NAT, select this box and
then type the public network IP address to be
displayed to the outside.
Used in combination with the DHCP option. When
the DHCP check box is selected, this option
allows you to obtain the DNS server address
automatically from a DHCP server in the network.
If you did not select the option for automatic DNS
address discovery, you must enter the
preferred/alternate DNS server addresses here for
the device to resolve domain names.
Sets the speed/duplex modes for LAN ports.
Supported speed/duplex modes include 10/100M,
Full Duplex or Half Duplex, and the 1000M
Network mode. You can also select Auto to use
Auto-Negotiation with the switch port.
Note: Contact the network administrator before
setting LAN Speed, to ensure that the switch
configuration is matched with the MCU port.
Specifies the Maximum Transmission Unit (MTU)
size used in IP calls and Web communications. If
the video becomes blocky or network errors occur,
packets may be too large; decrease the MTU. If
the network is burdened with unnecessary
overhead, packets may be too small; increase the
MTU.
