You are not mistaken. Setting this option is not currently supported in the native UDP implementation. > If not, what's the way to request a enhancement for Artemis that would include this feature? You can find details about how to request an enhancement here [1]. In short, you need to request a Jira account [2] and then open a feature request Jira here [3]. In the mean-time I believe you should be able to use the JGroups integration [4] for your use-case. I think the "ip_ttl" parameter on the UDP transport [5] is what you're after.
