any support for PPPoE ????? when gateway information is dynamic about wanfailoverscript HOT 3 OPEN

Can you elaborate on the exact issue you have? Do you have any suggestions for 
a fix?

your script works fine with Static ip configuration ..
but in a case of PPPOE . what sould be the values in wfs.conf

any support for dialer ??????? if one dialer failed then 2nd got up 
automatically?
since traffic is being forward to PPP0 interface

# WFS - Wan Failover Script
# Configuration file
#
TARGETS_FILE=/etc/wfs/targets.txt
PRIMARY_GW=ppp0 >>>>>>>>>>>> in case of PPPoE
SECONDARY_GW=10.10.1.2
INTERVAL=20
TEST_COUNT=2
THRESHOLD=3
COOLDOWNDELAY=30
MAIL_TARGET=""
DAEMON=1
QUIET=1
PIDFILE=/var/run/wfs.pid
PRIMARY_CMD=""
SECONDARY_CMD=""
DEBUG=0

I personally have no need for this. I probably never will. WFS works based on 
the assumption that static IP addresses are used. It would take some serious 
rework to make all that stuff automatic, if that's even possible.

I'm willing to consider proper patches though.
