in between posting and receiving your reply i have investigated a little more and discovered that i seem to be firewalled but don't know why.
the brickwall is showing on the globe icon in the bottom left corner of LW.
it seems from looking in the history of my antivirus (NORTON 2005) that it is blocking a worm intrusion.
have my settings allowing all LW stuff so i'm confused.maybe worm not to do with LW?????????????????
have used the link to check the port6346 and was ok.
am i going to hav to try the portforward thing or should i still try the first suggestion/

thanx for helping
