RDP from an external network - Remote desktop access from an external network

Question

Hello, I would like to remotely access my computer from an external network. The router I have is TPLINK TL-WR740N. 1. I have set the IP address of the computer I want to access to 192.168.1.102 2. I set the redirection of port 3389 to the address 192.168.1.102 in the Forwarding -> virtual...

Where do you get the internet from? Sometimes a client has a private address, not a public one. Then what you see when checking http://twojeip.wp.pl/ is the public address, but the provider's address, and there is some provider's router on the way. It's best to check your address on your router in the WAN tab, or "General".
For example, it can block a firewall on your computer. There may be RDP access there, but from the LAN (and from the LAN it works), and here comes the packet with the internet address, and that is untrusted for the firewall.

You have several options: - purchasing a public IP address from an internet provider - TeamViver application for remote access - purchase of an account for VPN or VPS servers with VPN service

-> my_external_IP: 3389 - port not needed Also check your firewall settings. EDIT: One more thing, and in fact it should be first: log in to your TP-LINK and show the summary screenshot, where you have the IP address on the WAN side.

What operating system? Is the user an administrator (or at least belongs to the remote desktop users group) and does he have a password? As colleagues wrote - add a rule allowing remote access to port 3389 to the firewall (Windows firewall).

czarnk · Answer

I turned off the firewall and antivirus completely, but I added an exception to the firewall just in case. The system I have is Windows 8. Indeed, in the WAN tab on the router I can see that I have the address 192.168.23.1.

So how do I get this remote access then?

Thanks for the reply.

czarnk · Answer

I was wondering if there is such a possibility (maybe total stupidity), redirect my external address (checked on yourip.wp.pl) on the provider's router to the address 192.168.23.1? And from my router, to any address on the local network?

I would not like to use TeamViewer, I will find out how much public IP costs, but I thought there was a free option.

I am trying to buy a Raspberry PI and I would like to have remote access there as well, because I want to try "playing with a smart home".

jimasek · Answer

I don't know your ISP's network configuration, at first glance it looks like a public IP address is shared by a few or a dozen users on your ISP's network.

czarnk · Answer

If it turned out that the address is assigned only to me (which seems to be a bit illogical then) is it physically possible to do it?

jimasek · Answer

Everything can be done except by the network administrator.

czarnk · Answer

@jimasek What do you think I should do best? Can I set something on the router? He will contact his internet provider if he can help me in some way. If he has nothing interesting to offer, I will ask about buying an IP, but it will probably not be the cheapest option. It will probably be better to buy an account on the VPN server.

jimasek · Answer

I would use TeamViver, I don't know what's the problem for you?

rwisniewski1 · Answer

And it's only for remote desktop? It's not worth it. As jimasek says: 1. Teamviewer - free for private use 2. let your ISP redirect some port to your IP, cost> = 0

jimasek · Answer

Some local suppliers are zdzierusy and they look to earn at every opportunity. Regards @ rwisniewski1

czarnk · Answer

Currently, only remote access, but as I wrote earlier, I want to buy a Raspberry Pi, and then I will need remote access to other things.
@ rwisniewski1 , but @jimasek wrote that it is likely the same public IP address, many people besides me. So what does the redirect look like? Is it possible then?

jimasek · Answer

I wrote that this has to be done by a network administrator. With more devices, it is good to think about some tunneling (VPN).

jprzedworski · Answer

This is why the administrator is unlikely to be willing to do such a redirect.

mickpr · Answer

And what does it bother you? In nothing!

hipekk · Answer

After all, the redirection is set to a specific port (and it does not have to be 3389 - for security you can change it) to a specific IP - so why would it be harmful? But the predecessors are right that he manages the network may want to earn on such stupidity ...

czarnk · Answer

I called my provider, he didn't have any problems and reportedly he redirected the public address to my address 192.168.23.132 on the spot. I am not able to check now, when I will be at home, I will let you know. Theoretically, after entering the public IP address, should I be able to access my router now?

m.jastrzebski · Answer

If the router has web support open to the outside then yes.

hipekk · Answer

It depends which ports it forwarded. If only 3389 - the default RDP port, you will not have access to your router from outside.

czarnk · Answer

I set up www access on my router and now I have public IP access. The supplier told me he had forwarded all the ports. Tomorrow I will check if port forwarding works, I want to set up Ubuntu on a virtual machine and set up a file server and a web server. Before I buy a Raspberry Pi, I would like to practice a bit on what is immediately available

czarnk · Answer

I have a problem again, I set up port forwarding. Port 3389, to connect remotely with my computer, wants to check if this port forwarding works for me, but I can't connect any more. I added antivirus and firewall rules off, firewall and antivirus rules just in case, but it still doesn't work. Via external_adres_ip: 8080 I can get to the router from outside, I was sure that then port forwarding would work. Got something wrong? What else could be the problem?

przeqpiciel · Answer

first of all - are you trying to enter from the same local network in which you have this server exposed? if so, try using 3g, from a friend from school, from work

czarnk · Answer

I'm at work and I'm trying to connect from there, I was trying to set up an FTP server on FileZilla and I wanted to connect to it, but also to no avail.

przeqpiciel · Answer

that is, from: work to: home so that there is no doubt.

you also write about virtual machine. When configuring network access of this virtual machine, did you set the network interface as a bridge to the network card?

czarnk · Answer

Yes, work -> home. He is currently working on physical devices. Let's leave the virtual machine alone for now From what I remember, I set it up as a bridge in the machine, I have to check it, because I put Linux up some time ago, but I didn't do anything on it.

przeqpiciel · Answer

so there is still the issue of earlier posts. Are you sure your network administrator redirected this port to you, because he may be using it himself ?! you would always try ngrok.com

czarnk · Answer

I think he redirected because earlier, after entering a public IP address, it redirected me to their router. Now, after entering public_address_ip: 8080, I can access my router. What's the easiest way to check if port forwarding is working, in addition to Remote Desktop?
