Part 2: Network Environment

If required, configure network proxies or override network speeds via the IBM Aspera Connect Browser Plug-in GUI.

If you need to configure any network proxies or override network speeds, you can do so through the IBM Aspera Connect Browser Plug-in Network option. Before modifying the Connect Browser Plug-In's network configuration, please review the network requirements, below, which describes ports that may need to be open on your network (e.g. 22, 33001, etc.).

Network Requirements

Your SSH outbound connection may differ based on your organization's unique network settings. Although TCP/22 is the default setting, 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:

Limit Transfer Rates

Important: Unless you need to limit the bandwidth used by the Connect Browser Plug-In, you should not set any values in these fields.

Launch the Connect Browser Plug-In (Start Menu > All Programs > Aspera > Aspera Connect) and open Preferences (System Tray > Right-click Aspera Connect > Preferences ).

You can limit the Connect Browser Plug-In's transfer rates via the Bandwidth option.

You may limit the download and/or upload transfer rates by enabling the respective checkboxes and inputting a rate in either Mbps or Kbps. Note that your ability to limit these rates depend on the following factors:

  1. Your network's bandwidth: Available bandwidth on your network may limit your transfer rate, even if you enter larger numbers into these fields.
  2. Your Aspera server transfer settings: Settings on your server may limit your transfer rate even if your network bandwidth and the numbers you enter are larger.

HTTP Fallback Proxy

The HTTP fallback proxy should only be used for fallback transfers, not for fasp transfers. To set up an HTTP fallback proxy, go to the Connect Browser Plug-In Preferences > Network.

Under the HTTP Proxy section, you can modify the proxy configuration for the server handling HTTP fallback. HTTP fallback serves as a secondary transfer method when the Internet connectivity required for Aspera accelerated transfers (i.e., UDP port 33001, by default) is unavailable. If UDP connectivity is lost or cannot be established, then the transfer will continue over the HTTP protocol based on this proxy configuration.

To configure an HTTP fallback proxy, select one of the following configurations from the drop-down list:

FASP Proxy

When fasp proxy is enabled, Aspera will pass the DNAT or DNATS (secure) username, server address and port to ascp. To set up a fasp proxy, go to the Connect Browser Plug-In Preferences > Network.

To configure a fasp proxy, enable the following checkbox(es):

Upon selecting the checkbox(es), input your proxy server username, password, address and port number.
