Configure your firewall with host names, port information, or IP address ranges to ensure MASV file transfers are permitted.
As a web-based app, MASV doesn’t usually require firewall configuration, but if you run into issues, you can configure your firewall with the host names or fully qualified domain names (FQDNs) and port information to ensure MASV file transfers are permitted. If you are working with the network layer, you can provide IP address ranges (AWS and Cloudflare) instead of host names.
Firewall settings
Firewall software is designed to protect your devices, network, and data, but it can also block applications and websites that you need to access. To avoid issues, you can use the information below to add MASV to your firewall whitelist or exceptions list.
Ports
All MASV endpoints use port 443. This port supports HTTPS (Hypertext Transfer Protocol Secure) to ensure communications are encrypted through Transport Layer Security (TLS).
Host names
Add the following host names, or FQDNs, to your allowlist (also known as a whitelist or exceptions list):
- api.massive.app
- api.massive.io
- massive.io
- get.massive.io
- app.massive.io
- help.massive.io
- *.portal.massive.io
- *.s3-accelerate.amazonaws.com
- *.cloudfront.net
IP addresses
If you are working on the network layer, you can whitelist IP addresses instead of host names. For MASV to work properly, you need to whitelist IP address ranges for both AWS (Amazon Web Services) and Cloudflare services. Please refer to the links below for the IP address information you need.
- AWS IP address ranges: https://ip-ranges.amazonaws.com/ip-ranges.json
- Cloudflare IP address ranges: https://www.cloudflare.com/ips/
