[OpenAFS] NAT issues resolved - 1.5.17

[Christopher D. Clausen]

On Windows, all problems I've had with NATed connections seem to be 
fixed when using 1.5.17.

1.5.16 - AFS was not usable behind NAT.
1.5.17 - works without problems (at least none so far)

The NAT "devices" I've tested with are a Belkin wireless G router and 
the Microsoft Windows Internet Connection Sharing feature.  I did not 
need to do any special configuration to have AFS work behind the NAT 
device.

Thanks to those who worked to fix all the NAT problems.
