Hi guys, We found when it was changed and the reason why:
https://issues.apache.org/jira/browse/CLOUDSTACK-4811 I already traced the code and we will change the NetUtils class in order to make it compliant with the RFC 3021 The fix will be on ACS 4.6.0 and back ported to the new release 4.4.4.

Left my mail in outbox and missed your reply ;-) @Sanjeev, since you answered the original mail.. Do you know when/where this check was added? Or else I’ll search for it. Let’s open an issue and resolve it.

Just as a matter of interest, why do you do this - we are presuming it does actually work ;) — Grts!

We have a lot of them already in place. As an example I pasted some output from cloudmonkey on a link that is already established and working. Does anyone have a workaround, or can point me in the right direction for a patch?
