All remote worker requests terminate on a single IP address on the external firewall. With the configuration rule on the firewall, the requests are translated into internal addresses and ports by using Network Address Translation (NAT). Customers must configure their external firewall to translate requests coming in on different ports towards the next application in the chain, which is the reverse proxy. The external firewall allows the requests to go to the reverse proxy.

The reverse proxy forwards the requests to the unique IP address and port to the internal firewall based on the path in the request URL.
