Model: Archer C6  
Hardware Version: V2
Firmware Version: 1.3.6 Build 20200902 rel.65591(4555)

Hello, i am trying to set up my router and desktop to be able to connect from outside my home network.

 

My desktop has a windows 10 pro version and remote desktop enabled. I can use the remote desktop windows client to connect from my laptop to my desktop when both devices are connected to my home wifi.

 

I have set up:

  1. DDNS server with no-ip to find my dynamic IP.
  2. DHCP server with fixed IP for my desktop PC
  3. PPTP VPN configured.
  4. NAT forwarding from external port 3389 to fixed desktop IP(point 2) with internal port 3389 (windows remote desktop connection uses port 3389)

 

When I ping the no-ip servername xxxx.ddns.net from my wifi-connected desktop i get the WAN IP for the router.

 

If i ping the same servername while connecting my desktop to another network (internet data over my mobile phone connection) i get the following:

"Reply from xxx.xxx.xxx.xxx: Destination host unreachable." Does anyone know why this is?

 

 

I have tried both:

  1. connecting to my router WAN IP first using the windows vpn tool.
  2. connecting directly with the remote desktop client to the pc using my router's WAN IP followed by ":3389"

 

but the "destination host unreachable" sounds to me like a connection from outside the home network is impossible

What you really need to get direct access from the Internet to your home router is a Public IPv4 address. (that is any IP address that does not fall within the IP address ranges I mentioned earlier)

 

However, based on what you said how the network in your apartment building is layed out, I think it is unlikely the ISP or network admin would be able to assign a Public IPv4 address to your network port or router. But you could still ask them.

 

If you can't get Windows remote desktop to work as you'd like, then maybe look if something like TeamViewer or similar software would allow you to achieve what you've planned to do. TeamViewer uses a different way to establish the connection between computers and doesn't require that your home router has a Public IP address.

Can you successfully establish a PPTP VPN connection to your Archer C6 via the Internet (i.e. from an external network)?

@woozle  I can not. This is the way the windows VPN is configured http://prntscr.com/1actcr9  and this is the error i get when i try to connect with my laptop over my mobile phone data.http://prntscr.com/1acton4. trying to ping the routers WAN IP results in the "Reply from xxx.xxx.xxx.xxx: Destination host unreachable." error i described above. The Ip i have used coincides with the one shown by the no-ip DDNS and also with the self reported ip in the Status section under my router's http://tplinkwifi.net

Does that IP address fall into one of the following IP address ranges?

 

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
100.64.0.0 - 100.127.255.255

 

If that was the case, then it would not work, because these are private or specially used IP addresses.

@woozle Yes, it falls under the 172.16.0.0 - 172.31.255.255  range. What does this mean? Can i fix it somehow? Need to call ISP?

Private IP addresses can't be reached from the Internet.

 

Sure, you can always call your ISP and ask if they can assist you with this issue.

 

How is your Internet connection set up? It is rather rare that a non-DSL or non-Cable, plain Wi-Fi router connects directly to the ISP. In most cases there is another "box" (e.g. pure modem, modem with router function, ONT) in between the broadband line and the user's own router. In case there is such a "box", do you have access to it?

@woozle Thanks a lot for your help so far.

 

I think the entire building has such a "box" to convert the glass fiber connection entering the building into the Ethernet connections we get in our apartments. So the ISP or the buildings community would have access to it. If i understand correctly I would first need a PPTP VPN through that box in order to connect to mi routers WAN IP?
