Wat u want i think could be doing a shortcut to ur PPPOE modem, well, my friend that's not possible.
The more appropriate term u should refer is the "adsl service" and not a link.
For fedora boys and girls, u can use the "setup" utility under the konsole mode. Choose "System Services" and u will see something like "pppoe" or "adsl", just check it and quit. Reboot ur linux.
But i must warn u that, "adsl-setup" which is the tool under the konsole for configuring adsl connection is not really reliable. Use the rp-pppoe instead.
That's my last advice. "rp-pppoe" is also know as Roaring Penguin -PPPOE. Coz existing pppoe in fedora have some known issues.
There rest is up to u to search, happy doing RND, i bet u will learn a lot by digging infos.
I can't give u straight answer as im no longer using Fedora anymore. But, this method definitely work.
