Help! Fetch hangs when connecting behind firewall (4 posts)

  I'm using Fetch 4.03 with Mac OS 10.2 behind a Symantec Gateway/Firewall 200 that only allows ACTIVE FTP connections.

  I've uncheckd the "Use passive transfer mode" in both fetch and the Network settings. However, I'm continuing to experience the same problems.

  I can connect fine to an internal FTP server, but I can't make any connections to outside FTP servers.

  Here's a sample Fetch Transcript:

  That's an unusual firewall setup; most only allow passive connections. With passive FTP all the connections go from the client to the server, and most firewall administrators find that less threatening than having connections coming back into the network from outside. Have you tried connecting with PASV turned on?

  Thanks,

  Thanks, Jim. Yes -- I have tried making a passive connection, and this also fails.

  The connection getts to:
  257 "/httpdocs" is current directory.
  PASV
  227 Entering Passive Mode (207,151,39,129,151,65).
  LIST

  and just hangs here until it times out.

  The Symantec Firewall is a pretty standard piece of equipment. Their docs say that they require active connections:

  "Using passive FTP with a virtual server
  Issue: Using passive FTP with a virtual server is not currently supported.
  Workaround: Use active FTP."

  Do you have any other suggestions? I'd sure like to be able to use my new Fetch software.

  Thanks,

  The Symantec FAQ for that product states "When you set up various applications, they may not function through the firewall unless you open ports for them. Virtual Servers and Custom Virtual Servers are for connections that initiate from outside your network; Special Applications are connections that initiate from inside your network." You aren't trying to access an FTP server inside your firewall from outside it, so I don't think the restriction on using passive mode with Virtual Servers applies to your situation.

  You may need to configure the firewall to allow all outbound TCP connections, and then use Fetch with passive mode enabled. Most firewalls come configured that way by default. Do any other FTP programs work through this firewall? For example, what happens when you enter:

  ftp://ftp.fetchsoftworks.com/

  in your web browser? Is your web browser configured to use a proxy server?
