A WebRamp Entree ISDN router can be configured to function as a
DHCP server.
This can be done through the router's command line configuration capability
by establishing a telnet connection to the router. When you have logged
into the router (the default userid is "wradmin"), you can check its dhcp
staruts by using the showdhcpopts command.
-> showdhcpopts
DHCP Module : Disabled
Domain Name : labyrinth.com
Gateway Address : 192.168. 1. 2
Subnetmask id : 255.255.255. 0
First DNS : 10. 22.111. 53
Second DNS : 205.197.182.100
Third DNS : 209.150.117.251
value = 0 = 0x0
In the above example, the router's DHCP server capability is disabled, though
it has already been set to provide a domain name, gateway address, subnet
mask, and DNS server addresses once the DHCP server capability is re-enabled.
You can change the information that it will provide to DHCP clients using the
setdhcpopts command. If you want help on the command you can isse
the command thelp "setdhcpopts (all arguments to the thelp
command must be includied in double quotes). Once you have set the
DHCP options, you can view them with the showdhcpopts command.
-> thelp "setdhcpopts"
Usage: setdhcpopts " { { -d < Domain Name > }
{ -g < Gateway Address > }
{ -n <-i> < ith DNS Address > } } "
Note : i = {1,2,3}
value = 0 = 0x0
-> setdhcpopts "-d labyrinth.com -g 192.168.1.2 -n -1 10.22.111.53"
value = 0 = 0x0
-> showdhcpopts
DHCP Module : Disabled
Domain Name : labyrinth.com
Gateway Address : 192.168. 1. 2
Subnetmask id : 255.255.255. 0
First DNS : 10. 22.111. 53
Second DNS : 205.197.182.100
Third DNS : 209.150.117.251
value = 0 = 0x0
With the "-d" option to setdhcpopts, you can set a domain
name to be assigned to DHCP clients. The "-g" option allows you to provide
the gateway address, in this case the address of of the router itself. The
"-n" option allows you to set the addresses of DNS servers to be assigned
to clients. The "-n" should be followed by another parameter, a dash
and a number that specifies which DNS server value is being assigned, e.g.
a "-1" for the first DNS server address or a "-2" for the second. That
parameter should be followed by the actual DNS server address.
To specify the range of IP addresses that the DHCP server will assign use
the setdhcp command.
-> thelp "setdhcp"
Usage: setdhcp " -a < Start of Address > -n < Number of Addresses > -f -p "
Note : The value of 'Number of Addresses' must be Greater than ZERO.
value = 0 = 0x0
-> setdhcp "-a 192.168.1.50 -n 10"
This operation may discard IP addresses that are previously assigned/reserved.
Are you sure you want to Continue?[y/n] :y
value = 0 = 0x0
The above setdhcp command sets the DHCP server to assign ten
addresses starting at 192.168.1.50.
To actually enable the router to start functioning as a DHCP server, you
need to use the enabledhcp. You need to follow that command with
the saveconfig command to make the change permanent.
-> enabledhcp
Do saveconfig to save changes
value = 0 = 0x0
-> saveconfig
value = 0 = 0x0
You can then exit from the router with the exitwr command.
-> exitwr
