[c-nsp] Backup/redundant internet connection

[Tim Franklin]

'outside' and 'inside' on the interfaces tell the router *when* to NAT.

'ip nat inside source list <acl> interface <interface> overload' tells the
router *what* to NAT.

The traditional config has the 'outside' interface and the interface in the
'ip nat' statement both as the WAN, but there's no reason why this must be
the case.

Tim.
