Have you successfully used LW at work at all? Is this the 1st time you've tried?
Is it possible to forward ports with the equipment at work? Wireless tend to use internal NAT firewalls. I presume these are ethernet.
Which version of OS & Java are you using at work?
I'm not sure about the reasons for your proxy settings for firefox. But if you're using proxy settings for LW then I think you need to have Socks v5 ticked & access port 6346 (LW's menu Tools>Options>Advanced>Proxy) Might also need to Force IP:
Force IP instructions & sample image & 2 posts after that.
