[vortex] Slow connection in local domain as well

[Otto Wyss]

I'm plagued probably with the same problem as was described in the thread "Slow
connection in local domain" in may. Unfortunately no final answer was posted and
I haven't found anything else on the net.

I have a Debian woody system (acting as a router) with two nics, one 3c509B
connected to the internet (cable modem) and one 3c905C-TX-M connected to the
internal network. Now everything seems to be okay when I download anything on an
internal computer (i.e. a PowerMac b&w G3) either from the internet or my Linux
router. But when I upload anything from the Mac to the Linux router, I get at
most a throughput of 5kB/sec. If I use the 3c509B for the internal network,
uploads are also okay. Unfortunately I can't use the 3c905C-TX-M on the internet
because of other reasons. My internal network uses a cheap 10BaseT hub.

Now here some outputs:

If I use the AppleSystemProfiler on the Mac I get the following network overview:
Link on, 10Mbit, half duplex. Now does anyone know what's wrong?
