Network Address Translation (NAT) enables multiple hosts on a local network to access the external (public) network by using a single IP address from their private internal network. The main benefits of NAT include efficient use of IP addresses, ease of administration, and security. On a J-series Services Router, NAT can be configured in different ways. For information about the types of NAT supported on Services Routers, see Network Address Translation.
You can use either the J-Web configuration editor or CLI configuration editor to configure NAT. NAT can be configured independently or with stateful firewall filters. For information about configuring NAT with stateful firewall filters, see Configuring Stateful Firewall Filters and NAT.
This chapter contains the following topics. For more information about NAT see the JUNOS Services Interfaces Configuration Guide.
