PC behind NAT

fkasmani · 01-16-2013, 03:19 AM

Hello,

I've got a remote headless PC that sit's behind the ISP's NAT firewall, meaning there's no public IP number.

This remote/headless PC successfully connects to reverse-ssh-tunnel and I can access it from anywhere by

Code:

ssh -p port# remoteuseid@middleip#

However, what I need is, to be able to access apps like Nagios & Webmin (that are installed on the remote/headless PC) so I can offer remote support to it. (point to note, the remote/headless PC is based on Ubuntu Server 12.04 Minimal, with no GUI)

Is this possible?

Would really appreciate some help on how to go about with this.

Regards.

Maybe a silly question: is a webserver installed and...running? Are the required ports open?

Just rambling along...

Well, it's not actually a web server to host web sites for the world; just acts as a server in a medical clinic for a Patient Record system which is web based. In addition to the Patient Recod system, there's things like Nagios and Webmin which are also installed for remote support and management.
Now, this PC sits behind the ISP's NAT firewall. However, I've successfully configured Reverse-SSH-Tunneling and can access this PC anytme & from anywhere with the SSH terminal.
Now I need to be able to log into it's Nagios & Webmin from remote locations with my web browser.

Someone suggested as follows:

you can use a SOCKS Proxy to access web apps. Look up examples of using ssh to create a Proxy - the tunneled connection works the same as any other ssh connection.

So I needed some assistance on this, pls.

Yes you could set up NAT or other means to access some private IP address behind a single public address. Do you have access to this perimeter device?
