Using RealOne Player or RealPlayer with Firewalls
Configuring a restrictive firewall to allow Player connection
A Personal Firewall is a consumer software application for the home user that usually resides on the machine being protected. The home user is the administrator of this application and can change firewall configuration. Unfortunately, these programs can sometimes be difficult to configure. Proper configuration allowing the Player access to the Internet will usually resolve any issues.
To rule out a personal firewall configuration as the problem, temporarily disable your security software and set your Internet Explorer security to default to attempt an unobstructed connection. If you are now able to connect, you must correctly configure your Personal Firewall to allow Player access to the Internet. The manufacturer of your firewall software will be able to assist you with this configuration.
A Network or Corporate Firewall is usually in a work environment with an intranet that allows access to the wider Internet. This firewall prevents outsiders from accessing the network’s private data, while also controlling what its own users have access to. A corporate firewall is often installed in a specially designated computer separate from the rest of the network so that no incoming request can get directly at private network resources. Only your Network Administrator can control configuration changes to the firewall. If the Player installer’s natural detection and general configuration advice fail to resolve connection issues in this environment, your Network Administrator will need to assist you.
If the network firewall is blocking Real IPs or servers by name, the Network Administrator will need to unblock them before the Player can connect to AU, Messaging Service, or any RealNetworks-broadcast audio or video. This configuration would not occur by accident or inadvertently.
If the network firewall is specifically blocking access to the Player software (realplay.exe), the Network Administrator will need to change this before the Player can connect.
Configuring Player to work from behind a firewall
By default, the Player uses the following ports to connect.
- TCP 80, 554, 4040, 7070, 8080, 443 (SSL for sign-in), 1755 (MMS Windows Media requests)
- UDP 6970-32,000, 1755 (MMS Windows Media resend requests)
- HTTP 80 (AU, Messaging Service, and HTTP Cloaking)
Player configurations will override these defaults. If these ports are restricted by your firewall, you will need to configure your Player Preferences to use your firewall’s settings.
