Port numbers, URLs, and IP addresses for GovCloud
Before deploying Workload Security in GovCloud, your network administrator needs to configure firewalls, AWS security groups, and web proxies to allow those network services. These parameters are limited in GovCloud to ensure secure connections:
Default settings are displayed. Many network settings are configurable. For example, if your network has a web proxy, you could configure agents to connect through it on port 1443, instead of directly to Workload Security on port 443. If you change the default settings, then firewalls must allow communications via the new settings.
The following network diagram provides an overview:
Required Workload Security IP addresses and port numbers
The following table is organized by source address (the deployment component which starts the TCP connection or UDP session). Replies (packets in the same connection but opposite direction, from the destination address) usually must be allowed, too.
Workload Security servers usually have dynamic IP addresses (that is, other computers in your deployment use DNS queries to find the current IP address of a Workload Security FQDN when required). For the list of Workload Security domain names, see Required Workload Security URLs.
Some ports are required only if you use specific components and features. Some services might have static IP addresses. These exceptions and optional features are indicated.
All ports in the table are destination ports (also known as listening ports). Like many software, Workload Security also uses a range of dynamic, ephemeral source ports when opening a socket. Rarely, ephemeral source ports might be blocked, which causes connectivity issues. If that happens, you must also open the source ports.

Localhost Only configure if the server's other software uses the same port (a port conflict), or if host firewalls such as iptables or Windows Firewall block localhost connections (server connecting internally to itself). Network firewalls do not need to allow this port because localhost connections do not reach the network. |

Required Workload Security URLs
Web proxies and URL filters can inspect the HTTP layer of connections: valid certificates, URL (such as /index), fully-qualified domain name (FQDN) (such as Host: store.example.com:8080), and more. Allow all URLs on every FQDN listed in the following table.
For example, agents and relays must be able to download software updates from files.trendmicro.com on port 80 or 443. You have allowed that TCP/IP connection on your firewall. However, the connection contains the HTTP or HTTPS protocol, which can be blocked not only by firewalls, but also by web proxies and web filters. Therefore you must configure them to allow https://files.trendmicro.com/ or http://files.trendmicro.com/ and all sub-URLs.
Some FQDNs are required only if you use specific components and features, as indicated.
