Re: [LARTC] QoS - Ping problem

Jody,

I think I have founded the problem.

This interface uses a Realtek RTL8139D network pci card. I have made 
many tests and I am thinking that this is the problem. When I sended all 
traffic to another network card (3Com 905-TXM) it worked fine. I will 
redo my concept about this hole thing.

Thanks for all answers I have get.

Att,

Nataniel Klug
