      I'm running into an issue with JNLP3. I have three slaves communicating through a proxy, so by the time the traffic gets to the master, they are coming from the same IP address. The port numbers are unique; they are ephemeral ports. With JNLP3, I can't get more than one slave connected at a time. Other slaves connect, but then I get a message:

      WARNING: Making

      {slave name}

      offline because it’s not responding

      If I remove the "-Djenkins.slaves.JnlpSlaveAgentProtocol3.enabled=true" switch (reverting to JNLP2), I can connect multiple slaves at the same time, no issues.
