Since the test doesn't work, your Limewire might very well be blocked by your network. That explanation about how you connect confuses me a bit as well (satellite connection)??

Try changing the listening port to a high number:
Go to Tools-->Options-->Advanced-->Firewall Config
Change it to something in the 50000-65000 range

Maybe try to change to portforwarding mode and use the same number, since by your explanation youy don't have a router anyway.

Add that same number to exceptions in your Firewall as well
