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 |
| 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-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. |
