I'm using *Camel-2.16* and I'm looking at the GitHub code for the
NettyProducer.java
<https://github.com/apache/camel/blob/camel-2.16.x/components/camel-netty4/src/main/java/org/apache/camel/component/netty4/NettyProducer.java>
, and I think the below highlighted code is what causes netty to specify
using an ephemeral port for the UDP source port when the camel-netty4
*udpConnectionlessSending* option is set to *true*. It would be nice if it
wasn't hard-coded and let you specify a UDP source port of your choosing!
I'm hoping someone with more knowledge will chime in.
// if udp connectionless sending is true we don't do a connect.
// we just send on the channel created with bind which means
// really fire and forget. You wont get an
PortUnreachableException
// if no one is listen on the port
if (!configuration.isUdpConnectionlessSending()) {
answer = connectionlessClientBootstrap.connect(new
InetSocketAddress(configuration.getHost(), configuration.getPort()));
} else {
*// bind and store channel so we can close it when stopping
answer = connectionlessClientBootstrap.bind(new
InetSocketAddress(0)).sync();*
Channel channel = answer.channel();
allChannels.add(channel);
}
