Example: Configuring Destination NAT on J-series Services Routers

JUNOS software with enhanced services allows you to define policies to translate the destination address from one IP address to another.

In this example, you perform the following tasks:

• Define a destination NAT (one-addr-dst-nat) with an IP address (20.1.1.1).
• Define a destination NAT (addr-range-dst-nat) with an IP address range (30.1.1.0 to 30.1.1.255).
• Define a destination NAT (addr-and-port-dst-nat) with an IP address (40.1.1.1) and a port number (8080).
• Define a reference (one-addr-dst-nat) in a policy (dst-nat-policy-1) to map a destination IP subnet (2.1.1.0/24) to address (20.1.1.1).
• Define a reference (addr-range-dst-nat) in a policy (dst-nat-policy-2) to map a destination IP subnet (3.1.1.0/24) to a subnet (30.1.1.0/24).
• Define a reference (addr-and-port-dst-nat) in a policy (dst-nat-policy-3) to map a destination IP subnet (4.1.1.0/24) and a port number (80) to an address (40.1.1.1) and a port number (8080).
