Putting my problem first:
I had Limewire working on a Windows XP computer. The computer "was" directly connected to OptusNet (Australia) via a Motorola Surfboard Cable modem with the WinXP SP2 firewall configured.

Then I had the bright idea to hook up all my gear on a LAN and I got a D-Link DIR-300.

Now I can't make Limewire work. So far I have
* turned off the WinXP SP2 firewall
* left the D-Link Dir-300 at factory settings which includes UPnP turned on
* installed the UPnP network service on the PC - the only change I noticed is my router now turns up in Network Neighbourhood and I have to tell my wife not to mess with it.

I will answer the questions as from the sticky:
1. OS version? WinXP - admin equiv user account.
2. What firewalls you have?
no software firewall now, setting the D-LINK DIR-300 is my problem.
3. How much ram?
504 mb - it worked before the d-link.
4. Hard Disk space available?
5GB+ - it worked before the d-link.
5. Connection type? (eg: dialup, broadband, cable, etc.)
cable broadband.
6. Modem & router brand name & model numbers? (eg: Linksys WRT54Gv4)
Cable modem: Motorola SURFboard cable modem connected via ethernet to
Router: D-LINK DIR-300 connected via ethernet to PC
7. Where are you trying to connect from (house, appartment complex, school, student accomodation, work, etc.)?
Own home
8. What version of LimeWire (LW) & Java do you have? (Go to LW's menu Help bar > About LW...)
Limewire 4.12.6 / Java 1.6.0_11
9. Who is your ISP (Internet Service Provider)?
Optusnet (Australia)
10. Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say 'Your test worked!'. What happens when you go there?
Your test worked!!
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up.
I have three PC's connected to the DIR-300. They connect successfully as a MS Workgroup.
Two computers have firewall rules preventing access to internet. The firewall rules used are based on their reserved DHCP assigned IP addresses.
I want one PC to have unrestricted access to the internet. That is the one I am posting from now. All applications I am currently using from this PC are working except for Limewire.
Those applications are:
FTP
Internet Explorer 8
Windows Update
Outlook (email)
Outlook Express (news)
Symantec Antivirus Live Update
12. Is this a your 1st try at LW or is this a new problem with an experienced user.
I already had limewire and used it for ages before I got the D-Link DIR-300, before I got that I was using the WinXP firewall without any problem.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Yes._
14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled?
UPnP is supposed to be enabled but I don't know anything about it.
15. What security programs are you using (antivirus etc)? Some people might not be aware that their security suite includes a firewall
Only security app is Symantec Antivirus Corporate Edition
16. What country are you living in?
Australia
17. Has anything in your setup changed recently? Have you updated your version of LW or Java? Have you added any new software or new hardware? Have you updated any software? Have you moved house, changed internet plan or ISP etc etc?
Problem started since I wanted to network my home PCs instead of just having one pc on the net.


Any/all assistance appreciated.
