tcp.invited_nodes
I think I already know the answer, but ...
At my manager's request, I started playing around with TCP.INVITED_NODES. What we wanted to find out was if we could specify a range of client ip addresses rather than listing each one individually. My initial tests indicate "no". The documentation never specifically addresses the question, but the way things are worded seem to indicate "no".
But, since "you never know what you don't know" .... I thought I'd ask.
On a closely related item, are there any special considerations on the use of TCP.INVITED_NODES if some of your clients are coming through a VPN?
