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).
Try debugging the netif layer. See if the PPP layer does set the IP address for the ppp interface, and if so, to what.
