This post will be about the NAT application of AR. Please find more information below.

1. Hosts on the Private Network Access Servers on the Public Network

Enable host inbound visit server outbound by configuring NAT.

2. Hosts on the Public Network Access Servers on the Private Network

Some servers such as Web servers and FTP servers inside private networks need to provide services to public networks. The NAT server mode supports this type of application.

3. Accessing a Private Server from a Private host Through the Domain Name

In DNS mapping mode, private network users can access private servers using the domain name by configuring the domain name mapping table, public IP address, public ports and protocol types, while establishing the mappings between the domain names of the private servers and the public network information.

NAT Multi-instance

NAT multi-instance allows hosts that belong to different MPLS VPNs but have the same private IP address to access a public network through the same egress device simultaneously. As shown in Figure 1, host A and host B have the same private IP address, but they belong to different VPNs. NAT associated with VPNs is enabled to differentiate the hosts in different VPNs. In this manner, host A and host B can access the public network server simultaneously.
