dynamic DNS is not really important - ISTM that your solution is to
move up the protocol stack. Markus's original problem was that the
restrictive nature of his client network was such that he couldn't
distinguish between requests at layer 3 (TCP). You're right that
layering the requests on a layer 4 protocol like http allows you to
distinguish requests by inserting the distinguishing label in a field
in http request header - eg the Host field, which can contain a domain
name and a port.

ISTM, it is not necessary for the domain inserted into the Host field
to be resolvable - if it is, then just distinguish on the port part -
so dynamic DNS is not necessary.

Cheers

anastomosis(circulatory) is the progressive branching of arteries down to 
capillaries.
The flow in the trunk line is accommodated by the sum of volumes downstream.
When such a network meshes with another closed network and the fluids in each 
are flowing in opposite directions. a counter-current
exchange system reduces the difference in gradients i.e. gases, heat flow.
Rete Mirable , the miraculous network that was first discovered in Tuna used to 
keep the blood warm.
There are  many such systems in the human body.

Sorry for being vague.  By "matrixification", I made an attempt to suggest 
something like taking a single 1-dimensional thing (a tube) and splitting it 
into more than one thing, each of which is still 1-dimensional, but together 
approaching a higher dimension (2 or 3).

By "articulation", I intended something similar, taking something like a single 
tube and putting in *joints*, which might also provide branch points.  Two 
pipes connected by an angle will be more articulated than a single pipe (of the 
same length).  By extension, then, 3 pipes connected by a splitter will be more 
articulated than two pipes connected by an angle.

Re: [FRIAM] virtualized public IPs

[Marcus Daniels]

Thanks Stephen and Gary.   Since what I’m doing at the moment is just with ssh, 
I can just use ProxyJump.
Good to know about the web-oriented ones too.   ZeroTierOne will have to wait 
for a few more free cycles, but that does look ideal.

Markus,

While not exactly virtualized IP, can you accomplish what you need via a 
dynamic DNS solution, ngrok.com or 
localtunnel.me and then manage routing on your internal 
network?

Hi,

The following seems like it is simple thing to address, but it doesn’t seem 
common.  Here are my assumptions:

1) I have several computers configured in complicated ways that I’d like to 
keep under my physical control.

2) I have an ordinary residential type of internet connection with one public 
IP.

3) I use various other computers, and some of them have irritatingly 
restrictive network policies.  I would like these computers to ask my computers 
to do things.
But they won’t route traffic on unusual ports to the internet.  So, for 
example, remapping ssh traffic to high ports and then using NAT to map them 
back on my end won’t work.
They also will refuse to allow VPN traffic to be initiated from their end.

I have looked at several VPN providers, but as far as I can tell all of them 
try as hard as possible to obfuscate the exit node.   I don’t want to do that, 
I want to have public points of contact, esp. for ssh that map directly back to 
me.

I suppose I could go to Azure or AWS and make a node do whatever I wanted, but 
I was hoping there was a standard service for this.   I don’t want to pay 
per-hour charges for compute that isn’t even compute.

Any ideas?Sorry for the pedestrian question.  We all know how important it 
is to have the best 
words.

Marcus

Re: [FRIAM] virtualized public IPs

[Gary Schiltz]

I struggled for years with a proprietary product called Hamachi (
http://vpn.net - a "zero config" "hole punching" VPN). It worked more or
less well to connect computers behind restrictive firewalls, but the Linux
version was in perpetual beta for years. Once the company and software were
bought by Logmein, it seems to be pretty well abandoned. I found an
actively developed, well supported open source alternative called Zero Tier
(https://github.com/zerotier/ZeroTierOne). I don't know if it will suit
you, but it works perfectly for my needs.

Markus,

While not exactly virtualized IP, can you accomplish what you need via a
dynamic DNS solution, ngrok.com or localtunnel.me and then manage routing
on your internal network?
