Yes, and I have a lot more information now. The bottom line is that I
suspect the wrong interface is being selected in camel-netty. Here are the
details:
I'm now testing a total of six interfaces on two machines. My VirtualBox
host is my Ubuntu laptop with three interfaces: localhost, vboxnet0 (the
VLAN), and wlan0 (my wi-fi card). The second machine is a virtual F19 with
localhost, p7p1 (the VLAN), and p2p1 (a NAT interface). I've disabled
firewalls on both machines and I'm running Wireshark on the Ubuntu host.
On the Ubuntu host, I ran NettyUDPAsyncTest using three URIs:
"netty:udp://localhost:{{port}}?sync=false"
"netty://udp://224.1.1.1:1201?sync=false&broadcast=true&networkInterface=wlan0"
"netty://udp://224.1.1.1:1201?sync=false&broadcast=true&networkInterface=vboxnet0"
Using localhost, the test passes and Wireshark shows UDP packets on
127.0.0.1. Using wlan0, the test passes and Wireshark shows UDP packets on
192.168.1.7=wlan0. However, using vboxnet0, the test fails but Wireshark
shows UDP packets on 192.168.1.7=wlan0, not 192.168.56.1=vboxnet0 ! It
looks like camel-netty is using wlan0 even when I specify vboxnet0.
On the F19 virt, I tried:
"netty:udp://localhost:{{port}}?sync=false"
"netty:udp://224.1.1.1:1201?sync=false&networkInterface=p2p1&broadcast=true"
"netty:udp://224.1.1.1:1201?sync=false&networkInterface=p7p1&broadcast=true"
On localhost and p2p1, the test passes. Wireshark sees nothing, which I
suppose is expected since the Ubuntu host is not connected to these
interfaces. On p7p1 (which is the goal of this exercise) the test fails
and, again, nothing shows on Wireshark. Given what is happening on the
Ubuntu host, I suspect that when I specify p7p1 on the F19 virt, camel-netty
is mistakenly sending on p2p1 and then trying to receive on p7p1.
I'm going to try debugging down through camel-netty, but if you have any
suggestions in the meantime, please advise.
