Hi Tom,

First of all, thank you for the reply. :)

I am aware that the sum exceeds the total bandwidth by far, but  the
number of hosts is under normal circumstances below 20. I just want to
make sure that  My plan was to decrease the bandwidth per host if/when
that number increase.

I know the line is limited but that's the resource I have available at
this time. I have tried upgrading to 20MBit, but without luck so far.

Do you think the matching rules are OK, and that the problem is the
number of them?

I have been using ipp2p before, but I have been having trouble making
it work with 2.6.22-gentoo-r9. I cant seem to enable it in the kernel.

What approach would you recommend to deal with P2P traffic overload?

Thanks in advance

Jesper
