No Ethernet connection under uClinux with MMU on 3c120 dev board

Hello,

I have problems to get telnet, ftp or http working on uClinux. I used the hardware example from the Altera Wiki for the 3c120 nios2_linux_3c120_125mhz_11.0sp1 with MMU.I followed the instruction on the wiki "Install Nios2 linux" and "Uclinux". I can compile Linux and dowload it on my board and boot it.

Boot screen:

but if i want to connect per telnet or ftp. its always connection timeout. and if i run ifconfig again, it seems that the board gets the packages but drops it.

i can also start the boa with

but cant connect either.

Has anyone an idea what i have done wrong or how i can fix it? Im new to FPGA's and im doing it for an university project.

Help would be appreciated!
