Notes Regarding On Demand Archive
The UDP ports used for on demand archives are randomly chosen. There are two
ways to configure firewalls and Windows Media Player for usage with Polycom®
RSS™ 4000 on demand archives.
1
Open an outbound UDP port range matching what is used by Windows Media
Player, or open all UDP ports outbound from Polycom® RSS™ 4000 to effectively
bypass the firewall for outbound traffic. Also open the port range used by
Windows Media Player for inbound traffic to the viewing PC. This range is
configurable in Windows Media Player, as seen in Figure 1 (Windows Media
Player defaults shown). The user can check RTSP/UDP, check ‘Use ports’ and
define the port range.
2 Disable UDP connections in Windows Media Player to force a TCP-only
connection. This configuration utilizes only TCP port 554. As seen in Figure 2,
disabling RTSP/UDP removes the user’s ability to specify a port range and forces
all connections to use TCP 554 only.
