Description
IP address of the primary DNS server.
Enter the IP address in dotted format notation, for example 10.8.2.255.
To use Fully Qualified Domain Names (FQDN) in the Tel to IP
Routing table, you must define this parameter.
IP address of the second DNS server.
Enter the IP address in dotted format notation, for example 10.8.2.255.
Disable [0] = Disable DHCP support on the gateway (default).
Enable [1] = Enable DHCP support on the gateway.
After the gateway is powered up, it attempts to communicate with a BootP
server. If a BootP server is not responding and if DHCP is enabled, then the
gateway attempts to get its IP address and other network parameters from
the DHCP server.
After you enable the DHCP Server (from the Web browser) follow
this procedure:
Click the Submit button.
Save the configuration using the Maintenance button (before
you reset the gateway). For information on how to save the
configuration, see
Reset the gateway directly (Web reset does not trigger the
BootP/DHCP procedure and the parameter DHCPEnable
reverts to 0).
Note that throughout the DHCP procedure the BootP/TFTP
application must be deactivated. Otherwise, the V7111 receives a
response from the BootP server instead of the DHCP server.
For additional information on DHCP, see
ini file note: The DHCPEnable is a special Hidden parameter.
Once defined and saved in flash memory, its assigned value does
not revert to its default even if the parameter doesn't appear in the
ini file.
Global gateway IP address.
Define if static Network Address Translation (NAT) device is used between
the gateway and the Internet.
Sets the DiffServ value for Network service class content.
The valid range is 0 to 56. The default value is 48.
