I turned on debugging. This is what I get when I try to telnet to the board
(192.168.1.4) from 192.168.1.3...... (0x401a8c0 is 192.168.1.4, the board):

ip_input: iphdr->dest 0xfb0000e0 netif->ip_addr 0x401a8c0 (0xe0, 0x1a8c0,
0xfb00000)ip_input: iphdr->dest 0xfb0000e0 netif->ip_addr 0x100007f (0xe0,
0x7f, 0xfb000000)
ip_input: packet not for us.
ip_forward: not bouncing packets back on incoming interface.


So basically, the data link layer (PPP) is up. But I am not able to do much
at the network layer (IP/ICMP).
