Mandrake and a new ISP

I have an internet broadband account with Insight Communications in which they are NOT PPP'ing me a dynamic address, as was the case with my previous ISP.

I've been toying with Mandrake Linux for a few months now and think i know which files to change to accomodate my ISP change. these are listed below.....

i got rid of the process that dealt with having my address PPP'd to me, called 'adsl' from
http://users.dslextreme.com/~craig.lawson/linux_notes/dsl.html
by typing 'chkconfig adsl off', and thats not starting at boottime now.

I guess I technically cheated in getting the following info by plugging the internet cable into my windows machine and typing 'ipconfig -all', after installing INsight's B#$%^& software and connecting that way....but i want to plug into my linux maching and use that as my gateway. i can connect internally to windows machines, but cannot ping my gateway at Insight. all this info is NOT changing when i reboot my windows machine, eventhough i have a dynamic accout:
