5.7 Traffic Redirect

Traffic redirect forwards traffic to a backup gateway when the P-660HWP-D1 cannot connect
to the Internet. An example is shown in the figure below.

Figure 44 Traffic Redirect Example

The following network topology allows you to avoid triangle route security issues when the
backup gateway is connected to the LAN. Use IP alias to configure the LAN into two or three
logical networks with the P-660HWP-D1 itself as the gateway for each LAN network. Put the
protected LAN in one subnet (Subnet 1 in the following figure) and the backup gateway in
another subnet (Subnet 2). Configure filters that allow packets from the protected LAN
(Subnet 1) to the backup gateway (Subnet 2).
P-660HWP-D1 User's Guide
DESCRIPTION
Maximum Burst Size (MBS) refers to the maximum number of cells that can be
sent at the peak rate. Type the MBS, which is less than 65535.
This feature is not applicable/available when you configure the P-660HWP-D1 to
use a static WAN IP address or in bridge mode.
Select Yes to set the P-660HWP-D1 to automatically detect the Internet connection
settings (such as the VCI/VPI numbers and the encapsulation method) from the
ISP and make the necessary configuration changes.
Select No to disable this feature. You must manually configure the P-660HWP-D1
for Internet access.
This feature is available when you select PPPoE encapsulation.
In addition to the P-660HWP-D1's built-in PPPoE client, you can enable PPPoE
pass through to allow up to ten hosts on the LAN to use PPPoE client software on
their computers to connect to the ISP via the P-660HWP-D1. Each host can have a
separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for application where NAT is not
appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use
PPPoE client software on their computers to connect to the ISP.
Type the MTU (Maximum Transmission Unit) your ISP recommends.
