NATand especially PAT/Masquerading is normally not a question of the routing
table/FIB, because it involves local addresses which are generally not
looked up in the routing table.
The state of a NAT connection is also not tracked in the routing table,
since it only contains configuration data. It may, however be linked to a
flow/routing cache.
Anyway, I dont know a device which is configuring even static n:m nat in the
routing table, anybody?
