Remote Access

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

Internet Access using ISDN Dial-up Services

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.

Internet

(WWW)

ISDN

INDeX

and IPNC

Local Area Network PCs

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.
