Firstly, take a look at this:

As for the Windows system, PPoE does not come into play.  

All you have to do is configure the network using DHCP, or manually using the 
freebsd box as the default gateway, and the first DNS server followed by your 
ISP's DNS servers.

If you just want a simple dialup router/firewall, and you have an old computer 
with a floppy drive and a hardware modem, and a NIC, then look at this:

I have had this working on a 486 with 8MB of RAM, no hard drive, no 
powersupply fan, no monitor, no case.
