Tunneling failed in Data Service 2.5.1

[rogierdoekes]

We created a set of application which all use Data Services
RTMP using port 2038. In the services-config.xml we set up in the
my-rtmp channel definition to use rtmpt as the protocol. All
applications are compiled with this service-config.xml.



For most users it is working fine, however for some of our
corporate user, behind restrictive firewalls, a connection to the
data services can not be made. The application throws a generic
send failed message.



Since we are using the rtmpt protocol, what can we do to make
sure our corporate users are able to use our applications?



Thanks,

It seemed the problem was fixed. However, as we set rtmpt as
the only channel, our other users were experiencing a big drop off
in performance due to the tunneling.



I read a very good blog entry:


http://www.infoaccelerator.net/blog/post.cfm/setting-up-rtmpt-failover-on-lcds

where Andrew talks about using rtmpt as failover for those
users that cannot use rtmp.



We implemented the structure he described:

- channel definition for rtmp in services-config.xml

- channel definition for rtmpt in services-config.xml

- channel definition for polling-amf in services-config.xml

- define both channels as default channels in
data-management-config.xml in the order rtmp, rtmpt, polling-amf



Everybody was able to use the data services..
