As a part of our effort to secure our test environments, we would like to explore how best to enforce IP restrictions on requests from our Auth0 dev environment to test environments.
Do our Auth0 environments route outbound/egress traffic through NAT gateways? If so, can Auth0 share with us static IPs from which we can expect traffic to come from?
The “NAT IP” is the IP used by Auth0 to call external services, such as SMTP server, Log Streams target, or external APIs called from rules, hooks, or custom DB scripts.
Getting the NAT IPs depends on your deployment option.
For customers in Public cloud, we recommend reviewing our Auth0 IP Addresses for Allow Lists documentation.
For all other customers, please open a Support Ticket to request your NAT IP addresses.
