Yes, i'll try:

 |          ROUTER     |       (also pppoe server using mpd)
    LAN     |
               |       |          |                      |
        user1     user2                        user n

ROUTER is a FreeBSD Box

user 1 ... user n are windows stations connected to pppoe server (win 
98, windows 2000 or win xp)

On the router is installed a dc++ server.
Users .... 1... to n are connected to dc++ server, they download files 
from each other.
The problem is that traffic from user 1 to user 2 , or between any user 
is going via  LAN nic.

If i do not use pppoe server and assign user1 .... user2 fixed ips then 
the traffic in lan is direct from a user to another. The traffic on LAN 
nic is not high.
So, pppoe will help in a easyer configuration of a client but traffic in 
lan is via LAN nic which is bad... if are many computers it slows down alot.

If user 1 download from user 2 a 700 mb iso it will take only 1 minute 
for a 100 mbps lan, but if pppoe is setup and many users download from 
each others the traffic lows down a lot... i had experience with 300 
kbytes/s instead of 8 mbytes/s.
