RealPlayer and ISA Server

Download RealPlayer - http://service.real.com/realplayer/down_in/ if the download manager does not work.

RealPlayer and ISA 2004

Create a firewall rule

Open ISA Management, go to the "Firewall Policy" node, click "Tasks" in the right frame of the screen, then choose "Create New Access Rule" which will take you through the following steps:

• rule name: RealPlayer Rule
• Allow rule
• Selected Protocols option and add the RTSP protocol from under the Streaming Media category
• From window you can choose Internal to permit requests from your internal clients
• To window you can choose Anywhere to permit such requests to any site on the Internet
• All Users to permit access from any user account

RealPlayer and ISA 2000

The only reliable way I found of getting the above to work (with RealPlayer 10) working with ISA in firewall mode was to do the following.

• Install the firewall client on the workstation.
  
• In ISA Server 2000
  Protocol Rule
  Set the Protocol Rule name of RealPlayer and applies to the protocols, MMS - Windows network, PNM - Realnetworks protocol (Client) and RTSP and set to Allow, set the rule to apply to a Client Set of All Clients.
  
  Extensions
  In Application Filters, right click HTTP Redirection Filter, in the Options tab select Send to requested Wbe Server.
  
• If not set manually set the http proxy in RealPlayer preferences to the ISA server.
  
• Last final section might not be required. (If required it will stop the logging of user account details)
  This final step requires you to switch off the "ask authenticated users for identification". (right click your server name under "server & arrays" -->properties-->"Outgoing web requests".
  Streaming should be reliable, although you may have issues banning users using ISA after that!
