Can´t reach my clients webserver

mlrtimbf

Hi,

I want to make a raspberry located in my local lan accessible from the internet via a VPN connection.

I have / want to have the following construction:
I have a VPS server @NetCup with a OpenVPN Server on it.
Thus works perfect! I can connect with a client to it and I have internet through this connection.
Now I connect my notebook (located in the internet) and my raspberry (located on my private LAN @ home) to this OpenVPN server.
I these client can "ping" each other, but my notebook can´t reach the webserver of the raspberry (on Port 8083).

Here is my server configuration (so Port 8083 listen on all interfaces):
[oconf]
proto udp
port 12345
dev tun
topology subnet

ca ca.crt
cert server.crt
key server.key
dh dh2048.pem

server 10.8.0.0 255.255.255.0

push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 208.67.222.222"
push "dhcp-option DNS 208.67.220.220"

And here the netstat output from my raspberry:

Somebody an idea? Do I have to make a Portfowarding on my local Router (OpenWRT)? IF so, which IP address do I have to forward?

Thanks
