Common Errors
 The inside or outside interface is not configured.
 The ACL configuration is incorrect.
10.4.3 Configuring Overlapping NAT
Networking
Requirements
When the same IP address is allocated to two private networks to interconnect with each other or the same global IP
address is allocated to a private network and a public network, this situation is called address overlapping. Two
overlapping network hosts cannot communicate, because both hosts consider that the peer host is in the local network.
Overlapping NAT is especially designed to implement the communications between two networks with the same IP
address. After overlapping NAT is configured, an extranet host address will be represented as another host address in the
intranet, and vice versa.
Notes
 Internal source address translation must be configured before overlapping NAT is configured.
 The newly configured NAT rules take effect on new flows only but not on any existing flows.
Configuration Steps
 Configuring the NAT Inside Interface
 Mandatory configuration.
