Chapter 5 Quick Setup
The Quick Setup allows the user to configure the ADSL router for DSL connectivity
and Internet access. It also guides the user though the WAN network setup first
and then the LAN interface setup. You can either manually customize the router or
follow the online instruction to set up the router.
The CT-5621 ADSL2+ multi-port router supports the following five network
operating modes over an ATM PVC WAN interface.
z
PPP over Ethernet (PPPoE)
z
PPP over ATM (PPPoA)
z
MAC Encapsulated Routing (MER)
z
IP over ATM (IPoA)
z
Bridging
The following configuration considerations apply:
z
The WAN network operating mode operation depends on the service provider’s
configuration on the Central Office side and Broadband Access Server for the
PVC
z
If the service provider provides PPPoE service, then the connection selection
depends on whether the LAN-side device (typically a PC) is running a PPPoE
client or whether the CT-5621 is to run the PPPoE client. The CT-5621 can
support both cases simultaneously.
z
If some or none of the LAN-side devices do not run PPPoE client, then select
PPPoE. If every LAN-side device is running a PPPoE client, then select Bridge
in PPPoE mode, CT-5621 also supports pass-through PPPoE sessions from the
LAN side while simultaneously running a PPPoE client for non-PPPoE LAN
devices. NAT and firewall are always enabled when PPPoE or PPPoA modes are
selected, but they can be enabled or disabled by the user when MER or IPoA is
selected, NAT and firewall are always disabled when Bridge mode is selected.
z
Depending on the network operating mode, and whether NAPT and firewall are
enabled or disabled, the main panel will display or hide the NAPT/Firewall menu.
For instance, at initial setup, the default network operating mode is Bridge.
The main panel will not show the NAPT and Firewall menu.
