14.The previous question enables the device to provide an IP address from a DHCP server to the client for use for the duration of the connection.

DHCP gateway (giaddr) interface: [] 10.0.0.15

15. The DHCP Gateway interface, or giaddr (as de®ned in RFC1531), is an IP

address associated with the subnet you wish the DHCP server to offer

addresses within. This is necessary because the DHCP server may be used to

lease addresses to more than one subnet. The giaddr allows the DHCP server

to distinguish from which subnet to offer addresses as well as provide an

address in which to respond to.

 

 

Quick Con®g will now ask you for an IP address to use as the giaddr. If you

leave this address as 0.0.0.0, the IP address of the interface used to reach the

DHCP server will be used. If you have only one LAN connected to the device

and your dial-in users will be given addresses on the same subnet as this

LAN, you can use 0.0.0.0 as this address.

 

Note: You will be permitted to enter an IP address here even if the address

does not yet exist on the interface. However, an interface must be

con®gured with this address before DHCP will work properly.

Do you want to use Dynamic DNS (requires hostnames to be configured for dial-in users)?

(Yes, No): [Yes]y

 

 

 

 

 

 

16. The response to the previous question determines if the router will instruct the

DHCP server to update the Dynamic DNS with the hostname and IP address

of a dial-in user.

 

 

 

If you will be using DHCP to administer IP address to your dial-in users, you

 

should answer yes to this question.

Is this information correct? (Yes, No, Quit): [Yes]

 

17.A summary of the information for DIALs con®guration is displayed and you are asked if it is correct. If the information is correct, answer yes. If it is not and you want to reenter the information, answer no. If you want to terminate quick con®g, answer quit.
