translation-type

Syntax

Hierarchy Level

Description

Specify the NAT translation types. To identify the interface cards and Junos OS releases that support each translations type, see Carrier-Grade NAT Feature Comparison for Junos Address Aware by Type of Interface Card.

Options

basic-nat44

Translate the source address statically (IPv4 to IPv4).

basic-nat66

Translate the source address statically (IPv6 to IPv6).

basic-nat-pt

Translate the addresses of IPv6 hosts as they originate sessions to the IPv4 hosts in the external domain. The basic-nat-pt option is always implemented with DNS ALG.

deterministic-napt44

Translate as deterministic NAPT44.

deterministic-napt64

Translate as deterministic NAPT64.

dnat-44

Translate the destination address statically (IPv4 to IPv4).

dynamic-nat44

Translate only the source address by dynamically choosing the NAT address from the source address pool.

napt-44

Translate the transport identifier of the IPv4 private network to a single IPv4 external address.

napt-66

Translate the transport identifier of the IPv6 private network to a single IPv6 external address.

napt-pt

Bind addresses in an IPv6 network with addresses in an IPv4 network and vice versa to provide transparent routing for the datagrams traversing between the address realms.

nptv6

Translate the source address prefix in a stateless manner (IPv6 to IPv6).

stateful-nat464

Implement 464XLAT Provider-Side Translater (PLAT) address translation for source IP addresses and IPv6 prefix removal translation for destination IPv4 addresses.

stateful-nat64

Implement dynamic address and port translation for source IP addresses (IPv6-to-IPv4) and prefix removal translation for the destination IP addresses (IPv6-to-IPv4).

twice-basic-nat-44

Translate the source and destination addresses statically (IPv4 to IPv4).

Note:

Starting with Junos OS Release 15.1R1, the twice NAT functionality (twice-basic-nat-44, twice-dynamic-nat-44, and twice-dynamic-napt-44 options) is supported on MX Series routers with MS-MPCs and MS-MICs.

twice-dynamic-nat-44

Translate the source address by dynamically choosing the NAT address from the source address pool. Translate the destination address statically.

twice-dynamic-napt-44

Translate the transport identifier of the IPv4 private network to a single IPv4 external address. Translate the destination address statically.
