Configuring network interfaces
Wait s seconds after power-up before activating this interface
The initial delay the router applies before activating the PPP instance after power-up. After the
initial power-up delay the normal always-on activation timers apply. If set to 0, no delay is
applied.
Keep this interface up for at least s seconds
The minimum period that the PPP interface should remain available. This means that even if
the link becomes inactive before this period expires, the connection will remain open.
Enable Multilink PPP on this interface
When enabled, enables the multilink PPP capability of the router. (See above for configuration
details).

Add a route to a.b.c.d if the peer's IP address is not negotiated
Normally, the IP address for a device connecting to a remote peer is assigned by the remote
peer. If this is not the case then the router will need a route to the remote peer. This setting is
set to the IP address of the remote peer so that it can be added to the routing table.
Enable DNS inbound blocking
Enables or disables blocking DNS requests on the PPP interface, to prevent the router from
responding to DNS requests over this interface.
Forward IP broadcasts over this interface if the interface is on the same IP network as
an Ethernet interface
When enabled, causes the router to route broadcast packets to and from Ethernet interfaces.
This will only occur if the PPP instance has issued an address which is part of the Ethernet
interface network.
Send LCP echo request packet to the remote peer
When enabled, displays the configuration parameters that cause the router to send Link
Control Protocol (LCP) packets to the remote peer at specified intervals. This feature can be
useful for keeping a link active (W-WAN, for example).
Send LCP echo requests every s seconds
The value in this text box sets the interval at which to send the packets. When set to 0,
transmission of LCP packets is disabled.
Disconnect the link after n failed echo requests
The number of consecutive failed echo requests allowed before the router terminates the link.
When set to 0, this functionality is disabled, such as the router will not terminate the link if the
LCP echo requests do not elicit a response from the remote.
Generate Heartbeats on this interface
When enabled, displays the configuration options controlling how the router sends heartbeat
packets. Generating a valid configuration enables the router to send heartbeat packets to the
