I am using EigerStein_contrib_img_pppoe-beta0.4.exe
I am having trouble getting the network.conf script to pick up the PPPoE
address from the ISP and defining $EXTERN_IP for the rest of the script. I
think it may be a timing issue, as I can run the part of the script that
extracts the $EXTERN_IP after the LRP is booted and it is OK. The
$EXTERN_IP ends up getting defined as 192.168.254.254 which messes up the
port forwarding stuff.
The portion of network.conf is below. How could I remedy this?
Thanks,
Kevin
