Consider the following example: suppose that PoeAC clients are connected through a wireless link.

Interesting chapter: Section 64.11.3, “How to configure a RAS using PPPoE connections with an Ethernet/WiFi network”. |
Configure the maximum number of PPPoE sessions with a value equal to the number of users which you want to enable (for example 10 users), configure the lower Eth100 resource (in this case: Eth-2) and give a name to the Access Concentrator.

Configuring the PPP-DNS-PRI and
PPP-DNS-SEC parameters in the IPRTR resource is
needed to redistribute the IP addresses of the DNS servers to the
clients.

NATNAT usage [NO; INSIDE;

LOCALClient Authentication protocol.
REMOTEServer Authentication protocol.
TCP-MSS-CLAMPIt decides whether to perform TCP MSS clamping; if set,
forces PPP to change value of Maximum Segment Size in all TCP
packets to one equal or lower than set with
TCP-MSS-VALUE option to avoid certain problems
with PPP over Ethernet “black hole”. Also can be used
to reduce link latency at the cost of some bandwidth loss.
DNSIt estabilishes the DNS addresses negotiation
[NO: no DNS address negotiation is performed;
PROVIDE: PPP can provide DNS addresses to a
remote host; RETRIEVE: PPP requests DNS
addresses from a remote host].
SERVICENAMEPPP over Ethernet Service name: name under which this link can be requested from the client. If the client specifies a certain ServiceName, Server answers only if it has link with tha exactly name. If Client specifies no name, it means any line is acceptable.
According to previous example, configure the IP over PPP resources with the following features:
LOWRES resource: POEAC-1;
server IP address: 192.168.10.201;
client IP address: 192.168.10.101;
service name: user_1;
enable TCP MSS clamping;
enable DNS negotiation;

To set act the changes made, use init res:ip-101 command followed by init ipr and save the configuration with save conf command to make the changes permanent. |
Repeat the same operations for each user by changing the number of
the IP resource (i.e. IP-102, IP-103…).
Add an entry in the Users table for each IP resource which you have activated.

The connection to the Access Concentrator can be done by using standard Windows PPPoE client or common routers that support this protocol.
