Try something else. Let's try Cabos: http://sourceforge.jp/projects/cabos/files/ & downld the SIT file. Cabos-0.5.7-MacOS.sit It'll be interesting to see if you can get results with this one. It's a combo between LW & Aquisition.

I had tried cabos it can not connect any other clients?

That was quick! How about Aquisition? Sorry ignore that it's not os 9 compatible.

I don't suppose you've considered upgrading to osx

OK back to LW, can you tell us about your option settings under Tools? Have you enabled or disabled Compression & locale preferencing? Do you allow simultaneous searches.

I think i need uPnP but i dont actually know what it is,
I cant connect gnutella network with cabos

Ive tried several combinaiton of options..
compression enabled or disabled and other settings

UPnP is Universal Plug & Play which if the router/modem has that ability, allows programs to communicate directly with it to open the necessary ports. Thus no manual port forwarding necessary. This was not introduced until LW 4.2 or 4.4 or so.

I wonder if you could choose a time of day when your friends might not be using LW & try using it then. If such a time exists. The problem as Stief suggested with OS 9 version is it's now quite old & many advances have been made to help with connection in difficult environments. With OS 9 LW you still had to use the Force IP option if you were firewalled. Have you tried it. It's mainly for incoming but it might be something to try. It's under the Tools>Options>Advanced options ...
I do recall it helped a couple of people at university. Try it!!!

I tried to use LW when others dont use, nothing has changed.
I tried to force ip option with several different port numbers nothing well happened.Which ports should i try? My problem goes on to make me sick

80, 443, 1111, 3500, 4008, 1203, 8080, 10000, 15189, 20282, 22817, 34599, 40475, 64049, 6295, 8360, 19515, 20285, 22091, 25079, 26394, 33307, 33049, 42628.

You need to apply each change & at least disconnect between each one. Then reconnect. Give it a min or so between each one's total disconnect.

The only other option I can think of is using a proxy. But that can be a long patient process. The thing is you can connect, but not search. It has all the markings of being filtered. Such as by your isp or school. Being well connected but giving zero search results suggests filtering by the ...

Proxy ideas: A Fix for those whose ISP's block Limewire pages 1 - 3 which have links to alternative instructions.

thank you for your time to help me let me try these ports now
