ac_cookie Specifies a tag that the access
concentrator may encapsulate in the
AC-Cookie tag in a PADO packet.
pppoesd generates a unique digest
using the MD5 algorithm. This tag aids
in protecting against denial of service
attacks. If a host receives this tag, it
must return the tag unmodified in the
following PADR. The tag value is binary
data of any value and length; the host
cannot interpret this value.
If you set this parameter to 0, pppoesd
does not add the AC-Cookie tag in a
PADO packet.
timeout Specifies the timeout value for PPP
session traffic in seconds. This is passed
as the idle timeout option for pppd.
retry_number Specifies the number of times pppoesd
retransmits a PADI or PADR packet
when the client does not receive a valid
PADO or PADS packet in response to its
request.
local-ipv4-address Specifies the address of the local
interface.
ipv4-address-pool Specifies a range of valid IP addresses
that the server allocates to its clients.
local-ipv6-identifier Specifies the interface identifier of the
local IPv6 interface.
ipv6-identifier-pool Specifies a range of valid IPv6 interface
identifiers that the server allocates to
its clients.
