Firewall Requirements
External Communication
The Collector only needs outbound access to 4 ip addresses, but it will need internal DNS or outbound DNS to a public DNS server (8.8.8.8 for example)
Outbound 443 to the following IP Addresses:
- 52.48.113.44
- 52.49.33.77

Outbound DNS to either a public DNS server, or internal DNS server which resolves public DNS addresses.
