Dynamic IP parameter allocation
The IPNC’s mode of operation for the DHCP Server is configured in the System Configuration form box.
With Server selected, IP addresses are allocated both to the LAN using DHCP and to dial in users during PPP link establishment. With
Dial– In users are allocated address from the LAN1 pool until all addresses are exhausted, at which point addresses from the LAN2 pool will be used.
DHCP Option | Notes |
|
|
IP address and Mask | Note 1 |
Router | System- IP Address (for LAN1) |
| System – IP Address 100Mbps (for LAN2) |
| Note 2 |
DNS Server Address | System/DNS |
| Note 3 |
DNS Domain | System/DNS |
WINS Server IP Address | System/DNS |
WINs Scope | System/DNS |
Notes: 1. The IPNC uses its system address+1 for the first IP address allocation (i.e. System IP address is 192.168.42.1 then the first IP address will be 192.168.42.2).
For dial in uses the IPNC allocates the top address as governed by the number set in the Number Of Address on the System Configuration DHCP tab. (i.e. System IP address is 192.168.42.1 and Number Of Address is 200 then the first IP address will be 192.168.42.200)
2.The IPNC offers either the LAN 1 or LAN2 IP address as the router dependant on which interfaces the request is made from.
3This is typically the IP address of an external DNS Server. If this is left blank, the IPNC will offer itself as a DNS server (within DHCP) and will forward DNS requests. The IPNC forward DNS request to the IP address of the DNS server learned in PPP link establishment. This option is controlled in the Service Configuration.
