Addendum:
I've seen question "Windows HTTP tunnel through 2 Linux hosts?" and trying to learn something about the answers. I learned. I will start giving my problem, and then talking a little about my tests with answers of that question.
I'm trying to connect my windows host to a linux host, using a middle linux (the only one with external IP).
What's my problem:
My windows host
doesn't have the ports I want open (game and traffic ports).
I have a linux host
that have the ports I want open.
So, the problem would be solved if I could make a ssh tunnel
through my windows host
to my linux host
. The problem is that both of then only have an internal IP (one is on my company, another is on my university).
The salvation: I have acces to my company's linux server
, that has an external IP (200.X.X.X).
So, I'd like to use this linux server
as an intermediate though my windows host
and my linux host
.
The complicating:
My linux server
only has the port 110 open. I can only connect through ssh to it using the 110 port.
In other words: I'm needing an example such that I can make:
windows host's
firefox, proxified to use localhost:9999
redirects its access to linux server
,
that redirects its access to my linux host
.
One (but not the only one) idea is reverse tunneling my linux host
to my linux server
, and then direct tunneling my windows host
to my linux server
, making this linux server
redirect my windows host
access to my linux host
.
But I do not know the commands to try that.
I tried, but with no success:
linux host: ssh -R 20000:localhost:22 middle_user@200.X.X.X -p110
windows host: ssh -L 9999:localhost:20000 middle_user@200.X.X.X -p110
How can I do that?
My environment, in another words:
Windows host
(internal IP == 10.X.X.X ; all ports open)
going through
Linux Server
(external IP == 200.X.X.X ; can only connect using ssh to it on port 110, the port 110 is the only open)
redirecting windows host traffic to
Linux Host
(internal IP == 192.X.X.X ; ports open, can connect using ssh on port 22)
Another addendum:
This would work if, on my linux server
, I could (in a perfect world) access my linux host
(what is impossible, given that I have an internal IP on my linux host
)
windows host: ssh -L 9999:localhost:9999 -D 9999 -p 110 middle_user@200.X.X.X
linux server: ssh -D 9999 linux_host_user@linux_host_ip
