Thwo possibilities.
1) Buy asnother ethernet card for your computer. Run a line from her
computer to yours. Haveyour computer act as a masquarading forwarder for
hers. This requires your macine to be on whenever hers is.

2) install an intelligent router which will make the connections with the
ISP. You and she just plug into the ethernet ports on the router.

The router will handle all the negotiations with the ISP.

First you turn off all firewalling. You find out what address the router
uses, and connect to it with http. You set it up.
Then when you know you can talk with it, and everything works, then set up
a firewall on your own machine.
