Trying to share a few files with a friend -- using LimeWire DIRECT CONNECT -- via IP address: we both can see and browse each other 's shared file list -- AOK!

But, when we try to download anything we see in that list, we each have this problem, same on both ends:

Queued... then Connecting... then Awaiting sources... forever!!!

Please help? What's causing this?? How can we fix it???

• We've tried and tried... waited and waited... and re-tried... again and again...
• We both use SBC Yahoo! DSL, and we live about 15 miles apart, fwiw.
• We have both put 6346 port forwarding into our DSL modem-firewall TCP port settings for LimeWire (using gateway.2wire.net). >> IS THIS SUFFICIENT? DO WE NEED TO DO ANYTHING ELSE? Proxies, whatevever, etc...
  
• Each of us can download popular files from the global network, after searching files by name, network-wide...
  
• When we search on each other's IP address, we can see the sweet list of files that we each want to share,
  
• BUT, we cannot initiate any successful downloads between us...
  
• We both have plenty of spare bandwidth, and open slots... so, that's not the cause...
  
• Otherwise, each of our LimeWire setups work just fine -- and we can see all the shared files on each other's systems via the LimeWire search / Direct Connect IP function... However, whenever we try to transfer any specific file from one IP to the other... no-go! Same result for either end:
  Status = Awaiting sources... forever...
