[c-nsp] NAT and ARP

[Brian Feeny]

Well one or all of the following should be really happening:

a) your using a NAT source list that only specifies truly valid 
networks, not something like "any any".
b) you are filtering so only valid networks can egress
c) you are using unicast revese path checking
