Network Address Translation (NAT)

Network Address Translation (NAT) performs IP address conservation to preserve the limited number of registered IPv4 addresses. It enables private IP networks that use unregistered IP addresses to connect to the Internet. The NAT feature on Citrix SD-WAN connects your private SD-WAN network with the public internet. It translates the private addresses in the internal network into a legal public address. NAT also ensures extra security by advertising only one address for the entire network to the internet, hiding the entire internal network. Citrix SD-WAN supports the following NAT types:

  • Static one-to-one NAT

  • Dynamic NAT (PAT- Port Address Translation)

  • Dynamic NAT with Port Forwarding rules

    Note

    The NAT capability can only be configured at the site level. There is no global configuration (templates) for NAT. All NAT policies are defined from a Source-NAT (“SNAT)” translation. Corresponding Destination-NAT (“DNAT”) rules are created automatically for the user.
