Configuring Inbound Net-To-Net Static Nat; Configuring Dynamic Nat - HP FlexNetwork MSR2003 Configuration Manual

Step
1. Enter system view.
2. Configure a one-to-one
mapping for inbound static
NAT.
3. Return to system view.
4. Enter interface view.
5. Enable static NAT on the
interface.

Configuring inbound net-to-net static NAT

For address translation from a public network to a private network, configure inbound net-to-net
static NAT.
•
When the source IP address of a packet from the public network matches the public address
range, the source IP address is translated into a private address in the private address range.
•
When the destination IP address of a packet from the private network matches the private
address range, the destination IP address is translated into a public address in the public
address range.
To configure inbound net-to-net static NAT:
Step
1. Enter system view.
2. Configure a net-to-net
mapping for inbound static
NAT.
3. Return to system view.
4. Enter interface view.
5. Enable static NAT on the
interface.

Configuring dynamic NAT

Dynamic NAT translates a group of private IP addresses into a smaller number of public addresses.
You can specify an address group (or the IP address of an interface) and an ACL to implement
dynamic NAT.
