In this configuration why would you assign the loopback interface
172.16.17.1?? Why wouldn't you advertise the 192.168.1.0 network? And
last but not least if your NATing to a 172.16.17.20 address how does
the external host send the packet back to the serial interface when it
has an address of 10.1.1.1? Would't the packet have a Source address of
the new nated address (172.16.17.20) and the destination of (External
Host)? How does it find its way back to the S0 10.1.1.1 network?
Thanks
