Webserver behind VPN

Hello everybody.

I use the MT300n-v2 for Openvpn Client.

at the PC (connect with the VPN Client) runs a Webserver on Port 84.

the portforwarding on my homerouter are correct.
But i cant reach the PC via ddns.
Local it works.
from homenetwork it works.
Tests:
the webinterface of the MT300 via Ddns…Works!
but no Client behint the MT300
Firewall on PC are disable.

What can i do?

Hi
You can add port forwarding based on VPN

dosn´t work for me.
Fritzbox Forwarding ddns-> gl-inet IP with internal and external Port 112
Gl-inet Forwarding external 112 via openvpn to lan on port 80

Can you draw your network topology or can I remotely support you with teamviewer?

Yes Teamviewer i have. But how wen can write Private? I draw a Picture

Sorry, I still don’t understand your network topology. I have the following questions:
1.fritzbox is a routing device, ddns running on fritzbox?
2. VPN Server running on fritzbox?
3.client network (gl-inet) What is the IP address of this device wan?
4. You want to access the PC via ddns on the 192.168.112.8 device (192.168.18.201)

Sorry, I still don’t understand your network topology. I have the following questions:
1.fritzbox is a routing device, ddns running on fritzbox?
Yes and yes
2. VPN Server running on fritzbox?
Vpn Seerver running on 192.168.112.10
3.client network (gl-inet) What is the IP address of this device wan?
192.168.18.1
4. You want to access the PC via ddns on the 192.168.112.8 device (192.168.18.201)
112.8 is a device at homenetwork and 18.201 are a device at clientnetwork.

i want access on 192.168.18.201.

If you are using a commercial VPN provider they need to enable incoming connection through the VPN. But not likely if it’s a shared server.

I am following the topology test you said.
