How to ensure your firewall works with MASV

Configure your firewall with host names and port information 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.

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 TCP or UDP. 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
