Please give us one more option to edit the PPPoE Connection for the WAN Interface

set link keep-alive 10 60

in /var/etc/mpd_wan.conf

@
set link keep-alive seconds max
This command enables the sending of LCP echo packets on the link. The first echo packet is sent after seconds seconds of quiet time (i.e., no frames received from the peer on that link). After seconds more seconds, another echo request is sent. If after max seconds of doing this no echo reply has been received yet, the link is brought down.

If seconds is zero, echo packets are disabled. The default values are five second intervals with a maximum no-reply time of forty.

This feature is especially useful with modems when the carrier detect signal is unreliable. However, in situations where lines are noisy and modems spend a lot of time retraining, the max value may need to be bumped up to a more generous value.

With this Feature I could even be able to Disable LCP echo request when I set it to ZERO.
So my WAN connection wound not go down and reconnect

most "Routers" like Sonicwall already have the option.
