Hi @karuturi,
Sorry, perhaps too earlier here, but I don't follow completely. :)
How did you setup your environment in order to test the case you explained
above? You mentioned that the rules were not there, and you had to set them up
manually. However, in the next comment, you said that is might have been caused
by restarting the network.
Did you run the tests in an isolated environment with a new built
systemvm.iso?
I just want to understand how you got that scenario - no rules. Based on
the new code and test, the only issue we got was the UDP/53 on the RVR.
If it was all caused by the network restart, then it's clear. And by the
way, that is another issue and I will have a look at.
Thanks again for the tests.
Cheers,
Wilder
