I did tried disabling STP, but it seems to create a loop and the board keeps recieving looped packets. I now have a packet sniffer on the board. When I ping to the board, I saw ARP request packets being sent to the forwarding port and being handed over to br0. br0 does generate ARP response but it never reaches the destination nor is it visible on the port at which the ARP request were received. The strange thing is that after a wait of about 20 minutes, I am able to start pinging the board again!!!!! Any clues????? __________________________________ Do you Yahoo!? Yahoo!
