What are the firewall requirements for the AeroFS Desktop Client?

We strive to have AeroFS work across all types of firewalls and environments.

At minimum AeroFS requires:

  • Ports 4433, 5222, 8084, 8888, and 29438 must be open for outbound connections on TCP.

For better performance, we recommend (but do not require) that you:

  • Allow inbound connections to the desktop client to facilitate LAN sync. You may restrict the inbound port range via Sync Settings in the management interface.
