Configuring the Firewall

Firewall settings required by the product.

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

Product	Firewall Configuration
Client	The following bullet points provide basic information for configuring your firewall to allow Aspera file transfers. Note that the outbound connection for SSH may differ based on your organization's unique network settings. Although TCP/22 is the default setting, please refer to your IT Department for questions related to which SSH port(s) are open for file transfer. Please also consult your specific Operating System's help documentation for specific 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: 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). Allow outbound connections from the Aspera client on the FASP UDP port (33001, by default). If you have a local firewall on your server (like `Windows Firewall`), verify that it is not blocking your SSH and FASP transfer ports (e.g. TCP/UDP 33001).
