I've done some searching. But, all I can find are tips for using LW behind a home firewall or software firewall. Is there a way to use it behind a corporate firewall?

Obviouslly, I cannot ask the IT dept to make changes in their firewall. What I need is a way to somehow squeeze through it, around whatever port blockage is preventing me from connecting.

Can I simply change the LW port to one that I know is not blocked? Or, is there a tunneling app that can VPN through an open port? Is there a Proxy out there open to the public?

Surely, people must have figured out how to use LW through the firewall at work. Please share it with me. I'm dyin' here.

BTW, it used to work fine. It sometimes took a bit longer than my pc at home. But, it still connected. Now, the firewall icon is in the status bar. So, they obviously made changes to their firewall to include LW.
