No network connection through hub

I have the following problem trying to connect my Suse 8.2 computer to
the lan.
When connecting it directly to a windows computer via a crossover
cable everything is ok (which proves the network cards work).
But I can't get a connection when using a hub!
Sending a ping from my linux host 192.168.0.1 to the other computer
with IP 192.168.0.170 results in the message "Destination Host
Unreachable".

I have tried several ports and different cables on the hub.
Within the windows network the hub works fine. (The hub is an old
4lan, 8 ports, model FH801D. It supports both 10 and 100 mbit. One
network card has 10 and the others 100mbit. When sending a ping the
lights on the network cards and on the hub show activity.


Once the internal lan connection works, the linux computer will be
used as a gateway (it already works with crossover cable).
It doesn't make a difference if I stop the firewall on my linux
computer or not.

Thanks in advance
Michael

Sounds like a routing problem check your route
route -n
this will show you your default gateway, you need to set the gateway to the
IP of the machine on the internet (or the next hop out if this is the
machine on the internet)

For instance
10.0.0.202 10.0.0.7 194.126.82.5
194.126.82.1
internal PC Firewall Box
Internet Gateway
default GW Default GW
unknown GW
10.0.0.7 194.126.82.1

as you can see the routing forwards the stream of outgoing packets to the
next machie in line, if you cannot get a route to host then your default
gateway is not set correctly
check using route and ifconfig.

I solved the problem. Seems that my old 10mbit isa ethernet card
didn't work correctly with the hub.
I replaced it by a 100mbit pci card and now everything is working
fine.

I can't understand why the hub lights and pings on the network card
worked correctly and the data wasn't transmitted.

Thanks
