Problem solved. Thank you for the debugging tip, Jasowill.Solution:We
had opened ports 2038,9100 and 8080 (tomcat) in
ourpc-firewalls.Apparantly RTMP is using port 2037 for the data,
although itis configured for 2038 in services-config.xml.After opening
port 2037 in the firewall everything worksfine, although this leaves me
with the question why port 2037 isused instead of 2038?Rui
