Hello, I am behind a restrictive firewall and the company policy is to not allow any inbound ports to be fully open. They have told me that if I initiate a connection from the inside, then the firewall will allow packets responding to mine through. My problem is that I want to run applications that connect to the access grid (www.accessgrid.org) and the server software sends back data on (possibly random) ports in addition to the one I initiated from my end. I am going to ask the developers if they could modify their software to initiate the new connections from the client side, but I was wondering if there is a tool that I could use to manually initiate connections over specified ports so that the firewall knows to allow the "responses" through.
