which technology they use for the backend in windows for remote access without internet?
here is the link -

In fact when you are not connect to internet you can not Access to other devices by remote access tools.in this case you can access to devices which are in your Local network only.
another condition is your device does not connect to internet directly but nearest your local router which has NAT configuration connected to internet and you use this router IP as gateway.so you are connected to internet and can remote access to other devices in your VLAN.
This may be my misunderstanding but you require a network connection to connect to Microsoft remote desktop..
No network connection no remote desktop.
Remote desktop works bt connecting across the network/Internet to TCP PORT 3389.
Now you "could" connect via modem but it would be so SLOOOOOWWWWW as to be basically unusable.
It is discussed here https://superuser.com/questions/992183/connect-2-pcs-together-via-the-pstn-using-dial-up-modems
Good luck

So, I've encountered a weird situation and am wondering whether you may have some suggestions as to how to investigate it...
I have a C# app that connects to Azure Blob Services using the latest SDK and TLS 1.2. When I am at home and on the Internet, I am able to upload files to blob storage without any issues. However, when I go into our office, using the same app on an office computer, I get a connection failure. I am able to access the Internet through a browser.
The networking is as simple as at my home... ISP connection, router/firewall, my computer.
I cannot imagine why enabling TLS1.2 would suddenly make my app not work in the office, but still work at home. Based on these tests, it seems like a NIC issue or an infrastructure issue at the office, but I have never heard of a NIC or router blocking TLS 1.2 outside of a VPN connection. There is no VPN involved.
I am planning on directly connecting my computer to the company's Internet connection, configuring the nic for the wan, and see what happens. If it works, then there must be something strange going on with the company's router (nothing elaborate; netgear, or such).
Has anyone encountered this issue? Seems really odd to me...
Thanks for your time and interest,
Mike
• It is not an issue with enabling of TLS 1.2 on your office network or your home network or even your Azure blob storage, it is basically related to the communication over SMB TCP port 445 from your local system to the mapped Azure blob storage on your system.
On your home network, you were able to access the blob storage and able to upload files in it because your ISP has enabled outbound communication over SMB TCP port 445 on his firewall and gateway server over the internet and thus, you were able to access the mapped Azure blob storage and upload files in it. But the same case is not valid for in your office network as it being a protected one, outbound communication over SMB TCP port 445 is restricted and not allowed.
• To test whether communication over TCP SMB port 445 can happen or not, I would request you to execute the below powershell command and check the results thereafter: -
Test-NetConnection -Port 445 -ComputerName somestoragexxx.file.core.windows.net
If this TCP 445 connectivity fails, then you could check with your ISP or your on-premises office network security is blocking communication over outbound port 445. Please note that you should open the outbound port instead of inbound port 445.

I have set up a new NAS using Open Media Vault. I have installed the WebMin extension to get on to the web gui for configuration. My problem is that I have to be on the same network as my NAS. How can I connect to my NAS from a different network than it is connected to? On the network that it is connected to its IP is 192.168.0.99:1000 for the WebMin gui. How can I access this from a different network?
Setup a VPN to connect to the network that your NAS is on. Once the VPN is connected you can connect to the NAS as if you were on the local network.
You could also possibly setup firewall and/or port forwarding rules depending on how your network is setup but please consider the security issues when doing so.
You could alternatively also try to open the NAS and give it a public IP address and a DNS. This will allow you to setup SSH and FTP as it was any other server.
To SSH remotely over the internet, you need either a permanent IP address or a domain name that is updated to point to the IP address when it changes. The latter requires a dynamic domain name service. A good free one is DuckDNS (duckdns.org). First, use one of the sign-in options such as Google. In the domain line enter your preferred subdomain name.
There is a great guide on how you can do this here: https://forums.freenas.org/index.php?threads/how-to-how-to-access-your-freenas-server-remotely-and-securely.27376/
I have a small server app, which receives UDP data on port X. When I run this app with a local logged in user account, all is fine and my app receives commands via UDP. But when I'm installing the app as a windows service which runs under same local user account, I'm not longer receiving data, when I try to connect from a different machine. Local connections are fine. I've also opened my UDP port X in the windows firewall settings, but with no luck.
Any help is appreciated.
Only for the sake of completeness:
It has been found that it has something to do with the virtual machine in which the Windows runs. I use a network bridge to connect it to my local network. After adding a host-only network adapter, my windows service received all expected commands. No idea why!?
I have set up a FTP server with Apache FTP server on local machine, this machine can access internet but its IP address cannot be accessed externally.
I also have another machine in a different city - it can access the internet but it is same in that its IP address cannot be accessed externally. The two computers are not on the same network so they are unable ping each other.
How I can use FTP client from another machine to access the FTP server, I know it should be impossible but do you guys have any workarounds (whatever code change or other approaches)
I am in the US - do you guys have idea how I can make my home IP publicly accessible?
it is very possible if you control the firewall that the server is behind. this is standard network configuration, and you can find hundreds of tutorials online, but the most important bit of information is the firewall, not the ftp server. you configure port forwarding on your firewall to forward incoming ftp requests to your internal ftp server. also, you will want to use "passive" ftp from the client because the client is also behind a firewall.
I googled, followed all the instructions but still stuck, and unable to create a home ftp server.
My internet is from dsl modem -> vonage router -> wifi router
FileZilla server ip is 127.0.0.1 and it works fine when tried from command prompt. But I need it to be accessible from outside.
I enabled ftp on wifi router's web settings page using virtual server setting.
I am stuck at this point, I don't know what else to do further. Any help is greatly appreciated.
Also, if you are planning on accessing your server remotely, (not in your network) you will have to enable port forwarding on your router. (Use the ip address of the machine running the server and use port 21) Otherwise, you only be able to connect while in your LAN.
This pretty much summarizes your needs(via lifehacker.com)
If you're FTP'ing across your home
network (like from your upstairs PC to
your bedroom PC), you can reach the
server by using its internal network
address (most likely something like
192.168.xx.xx.) From the command line, type ipconfig to see what that address
is. If you want to log into your FTP
server over the internet, set up a
memorable URL for it and allow
connections from outside your network.
To do so, check out how to assign a
domain name to your home server and
how to access your home server behind
a router and firewall.

You need to be able to access your internal network from the internet. Consider using a service like dynDNS if your router supports it.
