OpenVPN Port Problem

Hi,

I'm trying to set up a Raspberry Pi as an OpenVPN server with my Windows PC as a client. I used pivpn to set up the server and create the client config and set up my router (TP-Link AC1600) to forward port 1194 to the pi. The connection is established but there is no change in the IP. When I check udp port 1194 on https://canyouseeme.org/ it is not externally visible. It must be open on the pi for the connection to work and my PlusNet firewall is off so my question is where else do I need to look? I read some similar posts where users were able to use port 443 but not 1194 so I tried exposing 443 to test that I was port forwarding correctly and that was visible.

Any suggestions much appreciated, thanks,

 

M,

Re: OpenVPN Port Problem

Hi,

Using a pi2, my openvpn server works fine, I do not use the default udp port. I used the instructions from www.pivpn.io

 

The IP address on the connecting device does not change but you should see a second IP address on the pc in 10.8.0.n range. 

Open a terminal "pivpn -c"w show connected devices on the pi. For testing install openvpn app on you phone and connect using 4g

Re: OpenVPN Port Problem

Thanks Dan. I've read about people with this setup working, its just that mine isn't working! I followed the pivpn instructions too apart from changing the port. Do you think that the port number is significant? pivpn -c lists the PC with a 10.8.0.n address but if i check https://www.whatsmyip.org/ the entry is exactly the same whether I connect to VPN or not. Same story with an Android client.

Re: OpenVPN Port Problem

If you test VPN whilst connected to your home network you won't see any change to your public address.

I use openvpn on my android phone. I see a vodafone IP before I start the app and my home public IP when openvpn is connected. In fact the openvpn app reports this IP address on my phone.

I doubt the port assigned would make a difference, I use my own port as it makes it more secure.
