Configuring the Firewall

Your Aspera transfer product requires access through specific ports. If you cannot establish the connection, review your local corporate firewall settings and remove the port restrictions accordingly.

Desktop Client

The following is basic information for configuring your firewall to allow Aspera file transfers. The outbound TCP port for SSH may differ depending on your organization's unique network settings. Although TCP/33001 is the default setting, refer to your IT Department for questions related to which SSH port(s) are open for file transfer. Consult your operating system's documentation for instructions on configuring your firewall. If your client host is behind a firewall that does not allow outbound connections, you will need to allow the following ports:

• Outbound TCP/33001: Allow outbound connections from the Aspera client on the TCP port (TCP/33001 by default, when connecting to a Windows server, or on another non-default port for other server operating systems).
• Outbound UDP/33001: Allow outbound connections from the Aspera client on the FASP UDP port (33001, by default).
• Local firewall: If you have a local firewall on the client (such as Windows Firewall), verify that it is not blocking your SSH and FASP transfer ports (such as TCP/UDP 33001).
