SOHOSpeed ADSL2/2+ Ethernet/Wireless Gateway User’s Manual
31
Domain The domain name is used in conjunction with the host
name to uniquely identify the SOHOSpeed. To access the web
pages of the SOHOSpeed you can type 192.168.1.1 (the IP
address) or mygateway1.ar7 (Host Name.Domain).
Enable DHCP
Server
Enables/disables DHCP. By default, your SOHOSpeed has the
DHCP server (LAN side) enabled. If you already have a DHCP
server running on your network, you must disable one of the
two DHCP servers.
Assign ISP
DNS,
SNTP
Enable/disables the
Assign ISP DNS, SNTP
feature when the
DHCP server of your SOHOSpeed has been enabled. To learn
more about the
Assign ISP DNS, SNTP
feature, refer to
‘‘Assign ISP DNS, SNTP’’.
Start IP
The Start IP Address is where the DHCP server starts issuing
IP addresses. This value must be greater than the IP address
value of the SOHOSpeed. For example, if the IP address of
the SOHOSpeed is 192.168.1.1 (default), then the starting IP
address must be 192.168.1.2 (or higher).
Note: If you change the start or end values, make sure the
values are still within the same subnet as the SOHOSpeed. In
other words, if the IP address of the SOHOSpeed is
192.168.1.1 (default) and you change the DHCP start/end IP
addresses to be 192.168.1.2/192.168.1.100, you cannot
communicate with the SOHOSpeed if your host has DHCP
enabled.
End IP
The End IP Address is where the DHCP server stops issuing
IP addresses. The ending address cannot exceed a subnet
limit of 254, hence the max value for the default gateway is
192.168.1.254. If the DHCP server runs out of DHCP
addresses, users do not get access to network resources. If
this happens, you can increase the Ending IP address (to the
limit of 254) or reduce the lease time.
Note: If you change the start or end values, make sure the
values are still within the same subnet as the IP address of the
SOHOSpeed. In other words, if the IP address of the
SOHOSpeed is 192.168.1.1 (default) and you change the
DHCP start/end IP addresses to be
192.168.1.2/192.168.1.100, you cannot communicate with the
SOHOSpeed if your host has DHCP enabled.
Lease
Time
The Lease Time is the amount of time that a network user is
allowed to maintain a network connection to the SOHOSpeed
using the current dynamic IP address. At the end of the Lease
Time, the lease is either renewed or a new IP is issued by the
DHCP server. The amount of time is in units of seconds. The
default value is 3600 seconds (1 hour). The maximum value is
999999 seconds (about 278 hours).
Enable DHCP
Relay
In addition to the DHCP server feature, the SOHOSpeed
supports the DHCP relay function. When the SOHOSpeed is
configured as DHCP server, it assigns the IP addresses to the
LAN clients. When the SOHOSpeed is configured as DHCP
relay, it is responsible for forwarding the requests and
responses negotiated between the DHCP clients and the
server.
Relay IP
The IP address of the DHCP relay server.
Server and
Relay Off
When the DHCP server and relay functions are turned off, the
network administrator must carefully configure the IP address,
Subnet Mask, and DNS settings of every host on your network.
Do not assign the same IP address to more than one host.
Also, your SOHOSpeed must reside on the same subnet as all
the other hosts.
