When connected to the Corente Services network, legacy Corente Clients must be provisioned by a DHCP server located on the LAN of their host Location. The DHCP server must serve each of the Corente Clients an IP address, network mask, and default gateway address, as well as DNS server and WINs server settings. You will not be able to create reservations for Corente Clients based on MAC address, since the MAC address used over the Corente Services network is not the actual MAC address used in each physical client machine. Instead, the MAC address is obtained via proxy.
A DHCP server simplifies administration of remote access clients enormously. Because it provides an IP address on the same subnet as the Location gateway, it enables users to access and use resources exactly as they would if their machine was plugged into the LAN itself. All of the domain security functions for users at work, such as logon scripts and automatic drive mappings, will now work easily over the Corente Services network connection for remote access users.
If you are already using a third-party DHCP server to provision computers on the Location gateway’s LAN, you should also use this server to provision Corente Clients. However, if you do not have a DHCP server on the Location gateway’s LAN, the Corente Services Gateway itself can be configured to handle this task for Corente Clients.
The address assignments served by the native DHCP server on the Location gateway will last for the duration of the Corente Client session while it is connected to this Location.
Perform the following steps to configure how addressing information will be served to Corente Clients on the Edit RAS Client DHCP Server screen of the Location form.
On the User Remote Access tab of the Location form, select the DHCP Server Support Configure button. The Edit RAS Client DHCP Server screen will be displayed.
Select the Enable RAS Client DHCP Server option to enable the DHCP server for Corente Clients.
If you would like, enter a DNS Suffix to be served to computers by DHCP. When these computers submit a name for DNS name resolution, this DNS suffix will be appended to that name.
Select either of the following options, if you would like:
Serve DNS with DHCP: This option enables you to select whether or not to pass DNS Server IP addresses with the DHCP leases. When this box is selected, Corente Clients will be served the DNS server addresses that you supplied in the Network tab of this Location form.
Serve WINS with DHCP: This option enables you to select whether or not to pass WINS Server IP addresses with the DHCP leases. (WINS is the network protocol used in Windows networking; the computer names you see in Network Neighborhood are all resolved into IP addresses, and vice versa, using WINS.)
When this box is checked, you must enter the IP addreses of the WINS servers on your network that will be served to Corente Clients:
Primary WINS: Enter the IP address of the primary WINS server used to resolve WINS names on your local network.
Secondary WINS: Enter the IP Address of the secondary WINS server that will be used to resolve names if the primary WINS server does not respond. You cannot enter a Secondary WINS address if you have not entered a Primary WINS entry.
NoteWhen creating a Corente Client account, if the Backhaul All Traffic option is not selected, the Corente Client will not receive WINS and DNS server addresses when served its IP address by DHCP.
When you select the Address Ranges tab at the bottom of the screen, this section enables you to create the address pools that will be served by the Location gateway. You can Edit or Delete any existing range in this section. To begin creating address pools for Corente Clients, select the Add button.
The Add DHCP Address Range window will be displayed.
Fill out this window as follows:
Include Address Range or Exclude Address Range: To start, make sure that the Include Address Range option is selected. This option indicates that the entire range you enter will be served by DHCP.
Start Address: Enter the lowest value of the address range in this field.
End Address: Enter the highest value of the address range in this field. If the address pool you would like to create contains only one IP address, you do not have to enter anything in this field.
Select the OK button to save this pool. The range will be listed in the Address Ranges section.
If you would like to exclude certain addresses from any of the address pools you have added, you can exclude these addresses by Adding another range and selecting the Exclude Address Range option. Then, enter the range of IP addresses that you would like to exclude in the Start Address and End Address fields, as described in Step 6. The address of the Location gateway is automatically excluded and does not need to be entered here.
Complete Steps 5 to 8 to enter as many address ranges as you would like the Location gateway to serve.
When you select the Reservations tab at the bottom of this screen, you can reserve specific IP addresses for Corente Clients that receive their addressing from the Location's DHCP server. You can Edit or Delete any existing reservation in this section. To add a reservation, select the Add button.
The Add DHCP Reservation screen will be displayed.
Fill out this screen as follows:
Client Name: Enter the name of the Corente Client.
IP Address: Enter the IP address that will be reserved by the Location's DHCP server for use by this Corente Client only. The Client will always receive this address from the DHCP server.
Reserved: When this checkbox is selected, the IP address you entered will be saved and assigned to the Corente Client whenever it receives its addressing via the Location's DHCP server.
Select the OK button to save this reservation. The range will be listed in the Reservations section.
Complete Steps 10 to 12 to enter as many reservations as you would like the Location gateway to serve.
When you have finished defining the address ranges and reservations to be served by DHCP, click the OK button. You will return to the User Remote Access tab.
