Trunk connection issue via Asteris GUI 2.0 - "Request S

All,
I have an Asterisk system that I cannot get to communicate with my SIP provider. The GUI 2.0 states, “Request Sent”, however, I get nothing back. I have no idea as to what I should do, some suggestions would be helpful, please.

Linksys Router RV082
Port Forwarding:
TCP/5060~5082 -> 10.2.1.99
