• When the destination IP address of a packet from the public matches the global-ip , the destination
IP address is translated into the local-ip .
To configure outbound one-to-one static NAT:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Configure a one-to-one
mapping for outbound static
NAT.
nat static outbound local-ip
[ vpn-instance local-name ]
g lobal-ip [ vpn-instance
global-name ] [ acl acl-number
[ reversible ] ]
By default, no mappings exist.
If you specify the
acl keyword,
NAT processes only packets
matching the permit statement in
the ACL.
3. Return to system view.

5. Enable static NAT on the
interface.

Configuring outbound net-to-net static NAT
For address translation between a private network and a public network, configure outbound net-to-net
static NAT on the interface that connects the external network.
•
When the source IP address of a packet from the private network matches the internal NAT address
pool, the source IP address is translated into a public address in the external NAT address pool.
•
When the destination IP address of a packet from the public network matches the external NAT
address pool, the destination IP address is translated into a private address in the internal NAT
address pool.
