Hello,

when using bittorrent on a computer in my LAN, m0n0wall drops about 10% of 
outgoing (or incoming, I don't know) packets (I used mtr to find out how many 
packets are dropped). The data transfer rates are miserable, and surfing 
across the web is almost impossible. When I stop the download, all values are 
normal again.

When using only one HTTP or FTP download, the download rates reach something 
about 90 kbyte/s, so it's not the data rate, but the connections/second that 
m0n0wall doesn't like.

I am using a PPTP ADSL connection (768/128 kbit/s). The same connection worked 
very well with IPCop and a home made Linux firewall based on Red Hat Linux 
7.3.

Regards,
Andreas Mueller

P.S.
Yes, there are legal things you can download with Bittorrent:
