Hi:

I have ported LWIP on to a board and trying to connect to my ISP through a
dial-up connection. But unfortunately I am struck with the following error "
IPCP: close reason=Could not determine remote IP address state 9 -> 4". For
debugging purpose, I tried to connect to the same ISP through Win2K dialup
and had no issues. If you can please tell me of the possible causes for the
failure. For better insight I am pasting some of the hyperterm prints from
LWIP:
