I need to be able to have a host on Network-A to be able to connect to a router on Network-C - with Network-B in the middle.
Is it possible to NAT an IP from Network-A to Network-B - then NAT the resultant Network-B IP to an IP on Network-C?

Hi
Assuming you mean NAT the source IP address then yes this is perfectly possible. You just set up your NAT translations on each router eg
Router A
ip nat inside source static 192.168.5.10 172.16.5.10
Router B
ip nat inside source static 172.16.5.10 10.1.1.5
where
192.168.5.0 is NET A
172.16.5.0 is NET B
10.1.1.0 is NET C

BTW: It's also possible to double NAT on a single router, useful when two networks address space overlaps.
