First off, being firewalled simply means you may only connect to other users who are NOT firewalled. That is all. It has nothing to do with stopping you from uploading except for uploading, or downloading, from other firewalled users (which you can't do).

When you setup the static IP, you need to coordinate that with your router. Sometimes the router is setup to only allow you to pick a static IP within a certain range - like use DHCP for IPs from 192.168.1.1 to 192.168.1.150 and then only allow static IPs in the range of 192.168.1.151 to 192.168.1.254. So, you need to see what your router is set up for.
