This is odd: "Allow HTTP traffic" and "Allow HTTPS traffic" unchecked, yet I can get in

I've got a VM instance. The "VM instance details" page show, "Allow HTTP traffic" and "Allow HTTPS traffic" unchecked, under "Firewalls," and yet I can easily reach the Tomcat server running on it.

I will note that under "Network tags," it lists two strings that show up as firewall rule names (and as the targets of those rules) on the "Firewall rules" page of "VPC network."

The funny thing is that, although I haven't touched this thing in over a month, I don't remember doing this, and neither is there anything about it in my notes, but there IS something very specific in my notes about checking those two boxes.

Looking at another VM instance, I see something vaguely similar, only without the exact match between the network tag and the VPC firewall rule name (although there IS an exact match with the "target" on the rule).

Did something get changed internally, without anybody telling me, to generate this?

James, keep in mind someone might have created a rule external to that page, check out VPC Network -- Firewall rules to see if you see an 80, its pretty easy to create 80 open to all instances from there.

I tried it myself, it only works where a rule allows it.

I know I was the only one who could have done it from here.
