Example (read as one long line):
PPPOE_TIMES='Mo-Fr:09-18:0.049:N
Mo-Fr:18-09:0.044:Y
Sa-Su:00-24:0.039:Y'
Important: Times used in *_TIMES have to cover the whole week. If that is not the case
a valid configuration can’t be build.
If the time ranges off all LC-default-route-circuits (“Y”) togethter don’t contain the com-
plete week there will be no default route in these gaps. There will be no internet access
possible at these times!
One more simple example:
PPPOE_TIMES='Mo-Su:00-24:0.0:Y'
for those using a flatrate.
One last comment to LC-routing: holidays are treated as Sundays.
*_FILTER fli4l hangs up automatically if there is no traffic over the pppoe interface in the
time specified in hangup timeout. Unfortunately also traffic from the outside counts
here, for example connection attempts by a P2P client such as eDonkey. Since you will
be contacted almost permanently from outside nowadays, it can happen that fli4l never
terminates the DSL connection.
Option *_FILTER comes to help here. Setting it to yes will only consider traffic that is
generated from your own machine and external traffic will be completely ignored. Since
incoming traffic usually means that the router or computers behind it respond by i.e
rejecting requests additionally some outgoing packets are ignored. Read here how this
exactly works:

DCForumID2/46.html.
A more detailed description of the expression and its usage is to be found in the appendix
but is only interesting if you want to make changes.
*_FILTER_EXPR Filter to use if *_FILTER is set to 'yes'.
*_MTU *_MRU These variables are optional and can be completely omitted.
With these optional variables the so-called MTU (maximum transmission unit) and the
MRU (maximum receive unit) can be set. By default MTU and MRU are set to 1492.
This setting should only be changed in special cases! These variables don’t exist for
OPT_PPTP.
*_NF_MSS For some providern these effects can occur:
• Webbrowser gets a connection but is unresponsive after that,
