Has anybody out there been successful with LimeWire DIRECT CONNECT via IP address, while using a DSL modem with built-in FIREWALL? {Specifically: SBC Yahoo! DSL with a 2wire (tm) brand modem} and if so, how did you configure it, please?

I am using Windows 2000 Pro.

My firewall is set to forward port 6346 to my PC for LimeWire.

My firewall IP is 67.124.__.___

My machine IP is 172.16.__.___

Connection Type: Ethernet

IP Address: 172.16.__.__

IP Address Allocation: DHCP

IP Address Type: Private (NAT)

My LimeWire connection says TURBOCHARGED... sharing 47 files.

I have seen many UPLOADS completing in the past... -- while using LimeWire 4.0.x, 4.2.x, ... otherwise, SAME PC, same DSL modem, etc... -- but since upgrading to LimeWire 4.8.1 today, NO uploads have started or completed yet, and I have been connected for two hours, or more. Something seems fishy...

UPDATE: Three more hours later, a few dozen guest uploads have been done -- I guess it DOES take awhile for a leaf node to get hooked into the LimeWire/Gnutella ultrapeer network ...

Help? Is there any hope to get our IP file transfers going? What to do?
