Figure 19: PPPoE configuratio n for standard ISPs

Most PPPoE ISP’s use a single control and data connection, and require username /

password credentials to login and authenticate the DSR with the ISP.

The ISP

connection type for this case is “PPPoE (Username/Password)”.

The GUI will

prompt you for authentication, service, and connection settings in order to establish

the PPPoE link.

For so

me ISP’s, most popular in Japan, the use of “

Japanese

Multiple PPPoE” is

required in order to establish concurrent primary and secondary PPPoE connections

between the DSR and the ISP.

The Primary connection is used for the bulk of data

and internet traffic and the Secondary PPPoE connection carries ISP specific (i.e.

control) traffic between the DSR and the ISP.

Figure 20: WAN configuratio n for Japane se Multiple PPPoE (part 1)

There are a few key elements of a multiple PPPoE connection:



Primary and secondary connections are concurrent



Each session has a DNS server source for domain name lookup, this can be assigned by

the ISP or configured through the GUI



The DSR acts as a DNS proxy for LAN users



Only HTTP requests that specif

ically identify the secondary connection’s domain name

(for example *.flets) will use the secondary profile to access the content available

through this secondary PPPoE terminal.

All other HTTP / HTTPS requests go through

the primary PPPoE connection.

When Japanese multiple PPPoE is configured and secondary connection is up, some predefined

routes are added on that interface. These routes are needed to access the internal domain of the

ISP where he hosts various services. These routes can even be configured through the static

routing page as well.

Russia L2TP and PPTP WAN

For Russia L2TP WAN connections, you can choose the address mode of the

connection to get an IP address from the ISP or configure a static IP address

provided by the ISP. For DHCP client connections, you can choose the MAC

address of the router to register with the ISP. In some cases you may need to clone

the LAN host’s MAC address if the ISP is register

ed with that LAN host.

Russia Dual Access PPPoE

For Russia dual access PPPoE connections, you can choose the address mode of the

connection to get an IP address from the ISP or configure a static IP address

provided by the ISP.

WAN Configuration in an IPv6 Network

Advanced > IPv6 > IPv6 WAN1 Config

For IPv6 WAN connections, this router can have a static IPv6 address or receive

connection information when configured as a DHCPv6 client. In the case where the

ISP assigns you a fixed address to access the internet, the static configuration

settings must be completed. In addition to the IPv6 address assigned to your router,

the IPv6 prefix length defined by the ISP is needed. The default IPv6 Gateway

address is the server at the ISP th at this router will connect to for accessing the

internet. The primary and secondary DNS servers on the

ISP’s IPv6 network are

used for resolving internet addresses, and these are provided along with the static IP

address and prefix length from the ISP.

When the ISP allows you to obtain the WAN IP settings via DHCP, you need to

provide details for the DHCPv6 client configuration. The DHCPv6 client on the

gateway can be either stateless or stateful. If a stateful client is selected the gateway

will connect

to the ISP’s DHCPv6 server for a leased address.

For stateless DHCP
