The IPNC can be configured to provide Remote Access for both Dial-up and Dial-
in IP connectivity. An example of both of these types of remote access is 
discussed in this section. 

Dial-up Services 
Internet Access using ISDN Dial-up Service 

Dial-in Access 
Dial-in Access for PC Modem/ TA using Callback 

The following configuration provides a simple example for Internet access. Using 
this configuration it will be possible to provide access to the Internet for any 
number of PCs attached to either LAN1 or LAN2 of the IPNC. 

Because this example configuration uses the NAT functionality of the IPNC it is 
not suitable for VoIP. 

ISDN 

Local Area Network PCs 

(WWW) 

 

 

The configuration makes the following assumptions. 
1.  There is not an existing DNS server on the Network. 
2.  The IPNC is configured as DHCP server and there is not another DHCP 

Server on the LAN. 

3.  All PCs on the LAN are running in DHCP client mode 
4.  No IP addresses (including DNS server) have been supplied by the ISP 
5.  The following Information has been supplied by the ISP 

• An Account Name 

• Account Password 

• Telephone Number 

6.  To access the resources on the Local LAN (internal) from the Internet 

(external) additional configuration for the Primary Address Translation 
(see page 129) is required. This is because this configuration utilises the 
Network Address Translation (NAT) function of the IPNC.
