I have a software firewall turned on & a NAT router, but I do not get a firewall icon at bottom of my LW program.

Such an indicator will mean people will "struggle" to upload from you. They need to 'push' thru & only a small % (if any) will be able to do that.

The firewall icon might be related to your Satellite connection. Other people have had problems with ISP's that use Sat.
