   Please see docs before confirming an issue @Spaceman1984 
   
http://docs.cloudstack.apache.org/en/latest/adminguide/networking/virtual_private_cloud_config.html?highlight=acl#about-network-acl-lists
   
   Specifically:
   
   `The default Network ACL is used when no ACL is associated. Default behavior 
is all the incoming traffic is blocked and outgoing traffic is allowed from the 
tiers...:`
   
   With this in mind ^^^, conduct the testing... - it is expected that your 
noACL tier was able to ping anything outside
   
   But the other "blocked by default..." egress issue:
   
   I think the documentaion is not correct - i.e. for VPC networks, I don't 
recall that there was ever an implementation that will by default block 
outgoing traffic (egress) on ACLS where some Egress rules allow some access - 
i.e. you would always want to add 0.0.0.0/0 deny rule - it's an EMPTY ALC that 
you want to populate your way - just like on any other router - you will 
explicitely add deny to 0.0.0.0:0 as the last rule in the ACL.
   
   I would prefer that we update the documentation on VPC ALC, instead of 
chaning the behaviour, unless some of you can confirm that this worked 
differently in previous ACS versions @rvalle ?
