OpenVPN will not connect

You don't need to fill in anything with the openvpn wizard, other then select the wan interface! You do not have to put in a IP.

What IP or fqdn is your client pointing to?

In the export wizard for your client, you can pick what you want the client to point to

ports should be open on the NAT.." i am stuck on here

Where does it say this???

So simple as that.... this was the solution... it was by me on interface IP address!!!! changed that to other and filled in my public IP on Other..

Another question, when i have created the OpenVPN via Wizard it have created an interface but not assigned in the assignments page. Do i need to assign that? (Without that VPN works now like a charm)

Available network ports: opvns1 (VPN)

No for Remote Access vpn setups you do not need to assign an interface.. You would adjust any firewall rules you wan in the openvpn tab on the firewall rules.

I think that should be now correct, have only one OpenVPN rule there.

When connected via my Phone with VPN i like to use my pfblocker settings such as AD blocker etc.. what do i need to fill in the DNS or do i need to set redirect gateway on Openvpn server settings?

johnpoz

Well you would need to make sure your phone is sending all traffic down the vpn, ie internet not just your networks behind pfsense. Yes this would be the redirect all traffic setting.

Also you will need to make sure pfsense IP is being given as dns. And will also want to make sure your remote vpn clients IP (the tunnel network) is allowed to query unbound.

This would be done via your ACLs on unbound settings. Out of the box unbound would not allow this vpn tunnel networks IP to query it.

I have now problem when with connecting via OpenVPN. I get this error on pfsense Logs when trying to connect from Mobile Phone.

- TLS Error: incoming packet authentication failed from [AF_INET]xxxxxxxx:yyyy

Undo the (latest) OpenVPN server settings change.
Or
Keep the OpenVPN server settings - ad export your OpenVPN client config again to be imported in your phone.

I just undo that, the first problem was the following error code, just i receive now this error on the pfsense logs when connecting from mobile or PC.

xxx.xxx.xxx.xxx TLS Error: TLS handshake failed

@erbalo said in OpenVPN will not connect:

xxx.xxx.xxx.xxx TLS Error: TLS handshake failed

The x.x.x.x is the IP of the device with the VPN client ?

Yes, it is.

Ok, Then this is as clear as it gets :

@gertjan said in OpenVPN will not connect:

TLS Error: TLS handshake failed

means : This :

or, more specific : one or more items in this list (marked with a red cross ) :

doesn't correspond with the OPVN client file (OpenVPN client settings).

The server disagrees with the client.
The servers throws out an 'error' : TLS Error: TLS handshake failed.

edit : and before you think : "why does this happen to me ?"
The answer is a solid : "go talk with the admin".
We all see this error ones in a while. Rarely, it works 'right away'.
( at least, it never did for me ;) )

What I normally do :
I compare the config file of the server and the client. These are small text files. Easy to read.
This is the old fashioned way of making to devices talk to each other : compare their settings on both sides - using a paper and pencil.

Btw : also compare your OpenVPN server version number - and the OpenVPN client version number. If they differ, you also have to read the OpenVPN doc of both version, that is, the details of all the settings used. You're good for a visit at openvpn.org - the section 'manual'.

Just you know an OpenVPN setup can be activated in less then 8 minutes : do this https://www.youtube.com/watch?v=jQHqPq7ftz4 ;)
