I'm having a similar issue: 
I can't connect to the specified ports.  I have enabled Port Forwarding on my router and I still can't search. 
 
I have tried the following 
1. Disable my firewall. 
2. Using Passive Mode. 
     RESULT: Searching Works. 
 
Second Option: 
1. Enable my firewall. 
2. Use Passive Mode. 
     RESULT: Searching Works. 
 
Third Option: 
1. Disable my firewall. 
2. Enable Port Forwarding 
3. Use Active Mode. 
     RESULT: Searching DOES NOT Work.

HELP! HELP !
