No way a pII 333 is to slow to handle 2Mbit/s, my old 486 can handle
that easily. You would have to trash the conntrack hashtable with
multiple attacks to even have a chance of getting it that slow.

I also believe there's a duplex-mismatch somewhere, probably between the
firewall and the internal network.
