Understanding NAT rule

[srikanth ath]

What does the below Nat means

access-list PAT_EXTRANET_HEALTH extended permit ip object-group RFC1918 host 1.1.1.1
nat (INSIDE) 25 access-list PAT_EXTRANET_HEALTH

route EXTRANET 1.1.1.1 255.255.255.255 10.10.10.10 1

[Karsten Iwen]

If someone coming from the RFC1918-range is communicating with the IP 1.1.1.1, then the traffic is NATted according to this NAT-rule. Look for a "global (EXTRANET) 25 ..." command to see how the traffic gets NATted.
