Nethostfs...

Heya, I have 3.40 OE-A installed with IR Shell 3.1 and it all works fine except the nethost. I have "SmallNethostGUI" which I have configured and it runs with nethostfs 1.5. I have forwarded all appropriate ports on my router (Netgear DG843 I think) and have configured windows firewall, I have also changed the appropriate settings in IR Shell Configurator but it still says "Initiating wifi connection" then after about 10 seconds throws up an error message. Any ideas? This is driving me nuts!

Thanks!
