Linda,
I have written this comment in my ip-up.local:
# ip-up.local
# Parameters:
# $1 = INTERFACE
# $2 = DEVICE
# $3 = SPEED
# $4 = LOCAL_IP (As given by ISP)
# $5 = REMOTE_IP (of ISP)
The ip-up.local will already have the two IP addresses in $4 and $5.
Just use them. You may start by just echo'ing them to see what is their
contents.
Regards
Gustav
