Should I enable NAT loopback?

The main benefit of NAT loopback is that it allows one to treat the router’s WAN address as if it were in a LAN. This is beneficial if you have a hostname connected to the IP address of your WAN or just if you want to be able to access services via your WAN address instead of dealing with the internal LAN address.

How does NAT loopback work?

NAT loopback enables a user on the trusted or optional networks to connect to a public server with the public IP address or domain name of the server, if the server is on the same physical Firebox interface. The company uses a 1-to-1 NAT rule to map the public IP address to the internal server.

How do I know if my router has a NAT loopback?

If a LAN-side client can make a connection attempt to the public IP address of your gateway, and it successfully gets a response back from the LAN-side server you had set up a port mapping for, then your gateway is doing NAT loopback.

What is loopback rule?

You can create loopback rules from destination NAT rules to allow internal hosts to communicate with other internal hosts over the external IP address or the domain name. For example, create a destination NAT rule to translate incoming traffic to your servers and create a loopback rule.

What is NAT loopback port forwarding?

NAT loopback… where a machine on the LAN is able to access another machine on the LAN via the external IP address of the LAN/router (with port forwarding set up on the router to direct requests to the appropriate machine on the LAN).

What is a LAN loopback?

NAT loopback is a feature which allows the access of a service via the WAN IP address from within your local network. For example, you have a web server hosted on your local network. This web server is accessible from the outside using a public IP that is assigned to it.

  1. Create the loopback interface using the interface loopback number global configuration command.
  2. Add a description. Although optional, it is a necessary component for documenting a network.
  3. Configure the IP address.

Is hairpin NAT secure?

1 Answer. Hairpin NAT just means that the external IP of the NAT router is also accessible from the internal IP address – see Wikipedia for more details. While one might probably construct an unusual use case where hair pinning is a security problem it is not a security problem in the usual use cases.
