LCP Echo Disable
Factory Default = Disabled
If checked, this option will disable the modem LCP Echo transmissions.
LCP Echo Failures
Indicates number of continuous LCP echo non-responses received before the PPP
session is terminated.
LCP Echo Duration
The interval between LCP Echo transmissions with responses.
LCP Echo Retry Duration The interval between LCP Echo after no response.
Tunneling
Factory Default = Enable
If Enabled, this option allows PPP traffic to be bridged to the WAN. This feature
allows you to use a PPPoE shim on the host computer to connect to the Internet
Service Provider, by bypassing the Router’s capability to do this.
Note: Tunneling is available in PPPoE mode only.
Note: The values for the IP Address, Gateway, DNS Primary, and DNS Secondary are all “Override of the value
obtained from the PPP connection,” They default to “0.0.0.0,” in which case the override is ignored. It is
recommended that you do not change the values unless your Internet service provider instructs you to do so.
