Question Realtek 8169 no ip with DHCP on SuSE 10

Hi all,

I have just replaced an old LAN card (3COM 3C595TX) with a brand new Sweex Gigabit (Realtek 8169)
card on my SuSE 10 Professional system. I have configured my Suse system as a router for my small home network. I have installed DHCP to give out IP adresses to my home LAN.
At the moment i have only one Windows XP machine left with onboard 1GBit ethernetcard on my LAN but it doesn't get an IP nr from my Suse Linux machine (via DHCP). It did work fine with the old 3COM card but this was only a 100MBit card. I am using a crosslinked cable between my WinXP machine and my new Realtek 8169 card (i have removed my 100MB switch to make sure that both lan card work on 1GBit).

I have tried to disable DHCP on my WinXP machine and just typed in a IP adress and that seems to work ok for browsing the internet. However SAMBA doesn't work anymore and using FTP works not as it supposed to be.
For example, if i download a large file (1GB) from my Linux pc to my WinXP machine i get a speed of aprrox. 90mbps/s (11mB/s) but if i upload a large file (1GB) from my WinXP machine to my Linux machine it gets around 170mbps/s (21mB/s).

Has anyone have any idea what could be wrong ?

Some extra information about my setup:
Linux PC:
Suse 10 Professional
kernel: 2.6.13-15.8-default
eth1:100MBit card (Linksys NC100 10/100 rev 11)
eth2:1000MBit card (RTL-8169 Gigabit Ethernet card rev 10)

LAN Setup:
ZyXEL Router Prestige 2602
(DHCP enabled -> connected to eth1 on Suse linux pc)
eth2 from Suse linux pc
WinXP 1GBit onboard LAN

I get the folling output from :
