Address pool types

154

One or more disjunctive DHCP server address pools can be created per existing SpeedTouch™ interface using the Address Pool table. The first address pool displayed in the table has the highest priority for a certain interface.

If you select one of the address pools, following fields become available:

Name:

The name of the DHCP server's address pool.

Interface:

The SpeedTouch™ interface for which the address pool applies.

Start address:

The start IP address of the DHCP server's address pool.

End address:

The end IP address of the DHCP server's address pool. Both the start and end IP address define the IP address range used by the DHCP server to assign leases.

Subnet mask:

The subnet mask of the DHCP server's address pool.

Lease time:

The maximum time a client is allowed to use the address.

Gateway:

The IP address that will be assigned to DHCP clients as their default gateway

Server:

The SpeedTouch™ IP address used as DHCP server address (applicable for SpeedTouch™ multi-homing).

Primary DNS Server:

The IP address of the primary DNS server.

Secondary DNS Server:

The IP address of the secondary DNS server.

The table header shows following pool properties in addition :

State : the current DHCP server's address pool state.

PPP: the PPP interface used to fill the DHCP server's address pool dynamically (dynamic pools only).

Two kinds of DHCP server address pools can be envisaged : Static address pools.

Dynamic address pools.

Static address pools are configured manually by the user (state = static); on the other hand dynamic pools are configured dynamically based on the PPP-IPCP parameters negotiated for a (Routed) PPP connection (PPP interface given in the PPP column). When the PPP connection is up (state = up), all pool properties are defined except for the lease time which has to be configured manually. At the moment the

PPPconnection goes down (state = down) the pool parameters are remain valid to preserve LAN connectivity. If the pool parameters have been changed after the PPP connection comes up again, all associated leases are updated as well.
