----------------------------------------------
Hi [~rajanik]
If you create a VM under that network, can the VM talk to the outside world? I
see the rule clearly, but last time I tried to go outside from a VM in a
network with default egress to DENY, I had to add an egress rule allowing
traffic.
I'm deploying a DC to have a look into it.
Cheers,
Wilder
