WARNING: There is a known issue after enabling the No-NAT with Manual Inbound firewall Early Access Feature. The UI shows the default inbound firewall rule as Deny Any Any, but if the inbound firewall table has no other rules created this will be enforced as an Allow Any Any rule. We are actively working on correcting this behavior. In the meantime, adding any rule to the inbound firewall will correct this behavior and the default rule will be enforced as expected.
