openvpn client not connecting

@Cleetus-Antony
This rather means, that setting a pfSense as DMZ on the ISP router is the common way to configure it, when you intend to run services in your network.This forward all incoming traffic to pfSense and you can control it there, which gives you better and more options.
-
@viragomann
I configured the DMZ section of the ISP router with the destination of WAN IP of the pfsense and it didnt make any difference. -
@Cleetus-Antony
If the WAN rule on pfSense doesn't show any hit there is obviously nothing forwarded.
So most probably the problem is in front of pfSense and there is not much we can help you.Does the router provide diagnostic tools or logs to help investigating to issue?
Maybe you can sniff the traffic on its WAN to see, if there are even OpenVPN packets arriving. -

To possible test : ping.
get and note your WAN ISP IP.
Get a phone app that can send out pings (remember to switch of Wifi !! No VPN activated neither !!). Or go to to your neighbor.
Ping your WAN ISP IP.Before you start pinging, set up a WAN ping sniffer :
and hit Start at the bottom.
If all goes well, you'll see lines like this :
Nothing comes in ?
That means nothing reached the WAN interface.@Cleetus-Antony said in openvpn client not connecting:
Does all this means that my ISP router is not functioning well in terms of port forwarding to reach the openvpn traffic to pfsense. ? Do I need a replacement ? My current brand is GX Earth-4222 Router
Your ISP router image shows me all the needed for a port forward (NAT or/and PAT)
What you need : go visit the ISP FAQ and documents about your router : how to implement a NAT or port forward rule.
Putting a VPN port forward in place is since 2019 considered 'common knowledge' and I really believe your router is capable of doing that. -
@Gertjan
Will try and update -
Like : router GX Earth-4222 port forward ?!

I can see hits now in openVPN for WAN interface. But not connecting.
Attached the logs. Please have a look.
-
Ok, progress !
Connections attempts are coming in now.Question : one of these is the IP you were using with your client OpenVPN device :
?
-
@Gertjan
infact, I do try from my office PC thru office wifi only. My IP is different than the listed ones. I wonder how this IPs r showing as origin. -

You are aware that every Internet device can access any IP ?
You can go wherever you want, so can everybody else.
What you are seeing are 'random' IP addresses that 'try' to connect to you WAN IP, protocol UDP, port 1194. They 'test' your OpenVPN.
This looks scary if you've never seen this before, but don't worry, OpenVPN was created to handle this situation. You are probably using certificates as an access control mechanism :
you can see these certificates - you saw them in the ovpn file you've exported to your client - and it's impossible to guess these.
You Office PC is a PC that uses the Internet to go to you OpenVPN? right ?
This Office PC should not be part of your pfSense LAN network.Normally, to test, you install this app on your phone (an iOS also exist) and you use your phone with the Wifi de activated. Use the data of your phone provider to connect to your ISP WAN IP.
You know it works, as connections are already reaching your OpenVPN server ^^ -
Ya I thought that "may" be some attack attempts. BUT:-
I am in UAE now and my home is in India where pfsense is located.
My home IP is 59.88.4.40
but openvpn client from my office pc is trying to connect to 117.196.173.241:1194.I am using dyndns at my pfsense end. As per my research this ip 117.196.173.241 doesnt belong to my dyndns.
This makes me kind of total confusions.
I tried both User auth as well as TLS modes.
Attached the latest openvpn log from pfsense. Plz chk if u can see anything interesting ?

My home IP is 59.88.4.xx
but openvpn client from my office pc is trying to connect to 117.196.173.241:1194.That makes no sense.
If you know your that the IP you need to contact is is 59.88.4.xx then why would you (have it) use 117.196.a.b ?
DynDNS issues ? Who cares. Handle that one later.
For now, set up the IP like :
export the Client OpenVPN config.
Import the config in the client.@Cleetus-Antony said in openvpn client not connecting:

Starting testing the user auth possibilities when you are able to reach 59.88.4.xx

@Gertjan
Sorry that I couldn't respond to u after the last talk.I managed connect the opnvpn from my work place to home pfsense server.
But I my open vpn adaptor is not getting gateway and dns.Please revert.
-
-
Yes sir, Thats what the adaptor is getting my tunnel network IP from 192.168.2.0 series when connected.
-
@Gertjan
I set the Device Mode in server configuration as "tun" only no "tap" . So I shudnt get TAP adaptor in my connected clients rt ?Is that matters for not getting GW and DNS in client ?
-
@Cleetus-Antony
When you set up a OpenVPN server using TUN, you have to create a corresponding (redo) your OpenVPN client side accordingly.
Actually, every time you change something on the server side, you have to redo your client config also.Normally, you export the openvon config on pfSense to an opvn file, and you import this file on your OpenVPN client.
-
@Gertjan
Thank u. But my server conf was "tun" only since starting not tap. Hav any clue why I am not getting GW and DNS ? -
@Cleetus-Antony said in openvpn client not connecting:

Your client side ( ? ) as showing a tap connection.
-
@Gertjan
Yes sir, Thats what bit confusing. Please let me know if u need to see any particular configuration in server, I can show the screenshot. My "Device mode" conf is tun only.
