Basically, before a net, I'd want to drop any user-dialed outgoing connection to avoid tying up those machines, but if someone dialed in, I'd want to keep that connection.
At first, I was going to try and have the physical repeater node be an NNX, but un-registered, connected to a hub node on the same server, but I can't connect to other nodes that way. Is there a combination of control states that could accomplish this? For example link disable, but allow incoming connections? I haven't been able to find documentation on the control state specifics.
