A few questions. It is always helpful to give as much information as possible, such as what OS is the main computer? What other OS are you running?
Just as Sandeep asked, and I would agree with him as RDP and LMI and GTMPC would all be MUCH faster; but why use AVG's firewall when Windows Firewall is excellent? Which port did you open for 61067? TCP, UDP, both? I would open both. The error message specifically mentions the port. Have you rebooted after setting it up? Are you using AVG's antivirus and firewall? Is it a suite?
