Firewall and Proxy Server Allowlist Reference
Objective
For F5 Distributed Cloud Services to function accurately in your environment, it is necessary to configure your firewall and/or proxy to allow connections to the IP addresses and/or domains provided in this reference guide.
This reference document lists the public IP addresses and domains associated with F5 Distributed Cloud that must be permitted in your firewall and/or proxy settings. For automation purposes, you can download the subnet ranges and domains to include in your network configuration by clicking here.
Important: Ideally, you want to only allow the F5 Distributed Cloud subnets, exclusively. This will ensure that only F5 Distributed Cloud Routed Traffic can reach your network, and thus prevent attackers from being able to circumnavigate the F5 Distributed Cloud Infrastructure.
Important: If your application remains stuck in the
connectingmode or encounters network errors, review your firewall or proxy settings and update the allowlist configuration to allow these IP addresses/domain connections and associated locations, such as Docker Registry.

Public IPv4 Address Ranges for Site Registration and Updates
To provision legacy CE sites, you must allow the following public IPv4 address ranges, especially if your firewall does not support domain-based permissions.
Additionally, note that port 65500 is reserved for local UI and API access, so you may want to consider blocking or allowing this port as needed.
Important: IP addresses have the potential to change without F5 being aware of it. For this reason, using domain-based permissions is the preferred method rather than using this list.
Configure your network firewall to allow connections to the public IPv4 address ranges specified in the table below:
| Geography | IP Address Ranges |
|---|---|
| All Geographies | 20.33.0.0/16 |
| All Geographies | 74.125.0.0/16 |
