Did that but nothing to see there
Well if you do not see anything there when you attempt to access vpn.. Then how would you connect? Pfsense can only work with traffic it actually sees.
You have something upstream blocking access then, so no you would never be able to connect to pfsense vpn until traffic actually gets to pfsense.
Thats right my problem, i can't get any traffic via VPN client to the pfsensen. I think should be somehting with my NAT port... What did you fill in here as Target IP address? Should that be the the Gateway IP address of my Pfsense?

What? The openvpn wizard will setup the firewall rule to pfsense wan address.. You would not be doing a port forward for openvpn. Unless openvpn server was behind pfsense, and that is going to have its own problems with most likely asymmetrical traffic flow.
Again if you do not see traffic on pfsense WAN, then how would openvpn work? You need to validate your client is actually trying to talk to PUBLIC pfsense wan IP.. or if you have something natting in front of pfsense. Than that PUBLIC ip and that whatever is natting in front of pfsense is sending to pfsense wan IP.

On the all off the tutorials people saying "Via Wizard hit at the end to create firewall rules also, ports should be open on the NAT.." i am stuck on here
I think there somehting with my openVPN config or OpenVPNexport. Because i don't see any traffic when connecting from client, that file is not correct or is not comunicating with that public IP. Also on that Wizard i don't see any option to fill my public IP address..
-
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?
-
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 - Authenticate/Decrypt packet error: packet HMAC authentication failed -

I have now problem
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. -

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 ?
No "help me" PM's please. Use the forum, the community will thank you.
Edit : and where are the logs ?? -

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 ;)
