thanks for your quick reply..
bit im still struggling..

yep, our netgear router( WGR614 v6) supports UPnP..so have turned off manual port fowarding in LW and enabled it in the router settings..so is there no need to forward any LW ports now???
both machines have unique listen on ports in LW

what about in the mac os x firewall settings? have tried having the firewall on and off..but with no succes either way yet..wat do u suggest??? have set up the firewall (when it's on ..i spose) to let port 6346 thru on both machines..should they both be letting thru the same port??? or should they be the listen on ports??

and have made both computers have their own static IP..cheers for those links..too easy really!

umm
but its still doing the same thing...i can download and search in LW (turbocharged connection) but as soon as i try to download a 2nd file it says ..needs more sources..and after it downloads the 1st file LW seems to loose connection..
and also if you open safari (or mail or MSN) up..it doesnt have a connection anymore..untill i reset the router and dsl modem....

and figured the bandwidth would be shared if both comps were using LW at the same time..but i dont see that happning all the time..

mac os x 10.4 on both machines..Dlink dsl modem (ethernet and airport) and the netgear WGR614 v6 router

anymore suggestions??
thanks!
