Firewall

Note: If you are behind a corporate Firewall or Proxy server, you may need to have it configured to view the webcast video stream.

Firewall/ Proxy Requirements for Windows Media Player:

• The webcast video is streamed over two protocols.

• TCP Unicast is streamed using the TCP protocol over port 1755. This is the default protocol and provides the highest performance.

• HTTP Unicast is streamed using the HTTP protocol over port 80. This is the fallback protocol and is somewhat less efficient than TCP, due to added HTTP overhead.

• If you are behind a firewall or proxy server, you may need to request changes to the firewall in order to be able to view the webcast.

• If your firewall is providing proxy services for HTTP port 80, you should be able to access the webcast video. In order to achieve higher performance, your firewall will need to proxy port 1755, or be open to that port and provide a Network Address Translation (NAT) to each computer viewing the webcast.

• The Media Player does not support SOCKS protocols. You may have success viewing the webcast through a SOCKS proxy server by using a SOCKS application called SocksCap32. This is not a supported implementation.

For specific requirements or for additon support, please contact your system administrator.
