Technical Help : Firewalls

If the computer you are using is behind a firewall, you may need to ask your network administrator to open certain network "ports" in order to receive the audio-video and java applets.

A firewall is a security device designed to protect networks from unauthorized access and harmful data (such as viruses) from entering. It sits between your computer's network and the internet. Sometimes firewalls are set up by default to block access to the ports on your computer that are used to receive java applets and streaming media. Our servers target these ports because they are the optimized for the delivery of streaming media and the continuous connection required of an online meeting.

Please ask your network administrator to contact us at info@mchcom.com to determine which ports to open.
