Port-forwarding + collisions

[Rudi Starcevic]

Hi,

I'm still working on why I have poor performance and have found some 
data I need to check as I'm not that familiar.

Below I have the output from ifconfig.
eth0 is my Internet NIC with eth1 my internal 192.168.0.x network.

On my eth0 NIC we can see there is 0 collisions

On eth1 we can see collisions:6810362

This must mean a problem on the 192 end.

These are colo servers which are configured by techs over there so I 
don't have physical access to these machines ...

What could cause such a problem I wonder ?

It seems highly likely that this may be the cause of my bandwidth problems.

It is quite surprising that there is problems as there is only two machines.
--------------------------------------
Windnows 192.x.x.x = Gigabit card

Gigabit Switch

Linux 192.x.x.x = 10/100 MB card
Linux 64.x.x.x = 10/100 MB card
--------------------------------------

Is there anything special I need to do on the Linux end ?
I am told it is all supposed to auto detect ..
