Hi，Marc, Jack
I make some progress but it was not solved.
I boot the ROACH by 'run mmcboot' and did not got an IP address. And then log in RAOCH as root and try issuing the commands:
dhclient -r
dhclient
ifconfig
Then ROACH was assigned an ip address. And can use telnet to login ROACH.
But when I reboot the ROACH, ROACH Network is still unreachable.I have to issuing the commands:dhclient again.
I also open two ports ( tcp port 53 and udp port 67) in the server.But it still does not work.
I think that the DHCP connection doesn't work during boot.But I do not the reason.
Could you give me some help?
