Lord of The Rings,

Thanks for your reply.

I am using both Airport and a ADSL Ethernet modem/router, but I am able to 'share' files.

I've been using Limewire but got fed up with it and have started to try out eDonkey. I'm able to download files and it looks as though I'm uploading them too (while they are downloading) it's just that the status bar on my eDonkey screen ssays that I'm unreachable.

Does this NAT thing mean that I'll not be able to increase my download speeds (currently about 3 kbps against an upload of about 29 kbps)?

I'm a wee bit baffled. This eDonkey thing although it may be a far wider network, seems to require a great deal more individual machine by machine tweaking (and therefore technie know how)...
