Thanks. I have tried the solution in the first thread link. But, I may not be doing it correctly. The current proxy and port options appear to be different in the current version of Limewire. In any case, it isn't working.

The solution for Optimum Online in the 2nd link doesn't apply to me, as I am behind a corp firewall at work, not an ISP related blockage.

My issue is that certain ports are blocked by our firewall, and I need to use a known good port, or a known good proxy, or some other method to tunnel out from behind the firewall. And, I need to be able to configure LW 4.10.9 accordingly.
