NAT (network address translation)
Rewriting the addresses in packets as they cross a boundary, so private addresses can reach the internet or two networks with overlapping addresses can talk.
In REAP
NAT rules are part of the security policy REAP evaluates before a change and part of the path evidence when a flow stops working after one.
