Jim,
My simple hub can not do any fancy NAT, it just makes PC and 7250
shared the same DSL modem. My PC has only one ethernet card,
therefore, I can not browse internet while working on the board. So, I
use the hub that connects both PC and 7250 and its uplink connects to
DSL modem. Then PC can communicate with 7250 and browse internet no
problem.
I use loadUSB.sh to change root to USB with debian, however, can not
use apt-get to install anything. It looks like 7250 can not
communicate with internet. "ping www.yahoo.com" from board does not
work. I am not sure whether I should config either board or PC. I am
quite new on network, please help me, thanks!
Thanks.
Tom
