3.2.1
Cable Internet with Dynamic IP Assignment
By default, Compex NetPassage 16A is pre-configured to support a WAN
type that dynamically obtain an IP address from the ISP. If you have
subscribed to Cable Internet of which your ISP dynamically assign an IP
address, you do not need to configure the WAN type.
However, there are exceptional cases where additional configuration is
required before an IP address is successfully obtained from the ISP:
Certain ISPs log the MAC address of the first device connected to the
broadband channel, and refuse to release an IP address unless the MAC
address matches the one in the log. If this is not a new Cable Internet
subscription and that the ISP refuses to release an IP address to you, you
may clone the “approved” MAC address to Compex NetPassage 16A.
Refer to the paragraph titled
Cloning MAC Address to Compex
NetPassage 16A
in this section.
Certain ISPs requires a DHCP Client ID to be authenticated before releasing
an IP address. To successfully obtain an IP address from such ISPs, you
need to configure Compex NetPassage 16A with a DHCP Client ID.
Compex NetPassage 16A uses
Router Identity
as the DHCP Client ID to
request for IP release. Refer to
Section 3.14.1
titled
Setting Router
Identity
.
If your Compex NetPassage 16A has previously been configured with other
WAN type, you may re-configure it to support Cable Internet with Dynamic
IP Assignment.
