active-filter option is given, data packets that are rejected by the
specified activity filter also count as the link being idle.
ipcp-accept-local
With this option, pppd accepts the peer’s idea of our local IP
address, even if the local IP address was specified in an option.
ipcp-accept-remote
With this option, pppd accepts the peer’s idea of its remote IP
address, even if the remote IP address was specified in an option.
ipcp-max-configure n
Sets the maximum number of IPCP configure-request
transmissions to
n (default 10).
ipcp-max-failure n
Sets the maximum number of IPCP configure-NAKs returned
before starting to send configure-rejects instead to
n
(default 10).
ipcp-max-terminate n
Sets the maximum number of IPCP terminate-request
transmissions to
n
(default 3).
ipcp-restart n
Sets the IPCP restart interval (retransmission timeout) to n
seconds (default 3).
lcp-echo-failure n
When this option is given, pppd presumes the peer to be dead if n
LCP echo-requests are sent without receiving a valid LCP echo-
reply. If this happens, pppd will terminate the connection. Use of
this option requires a non-zero value for the lcp-echo interval
parameter. This option can be used to enable pppd to terminate
after the physical connection has been broken (for example, the
modem has hung up) in situations where no hardware modem
control lines are available.
lcp-echo-interval n
When this option is given, pppd sends an LCP echo-request frame
to the peer every
n seconds. Normally the peer should respond to
the echo-request by sending an echo-reply. This option can be
used with the lcp-echo-failure option to detect that the peer is no
longer connected.
