Edit: First off, I just realized this is the wrong forum for this post, but I don’t see how to delete it. so I apologize up front for the incorrect post location.
Hello, so I used the pfSense openVPN wizard to create a VPN server and export a client ovpn file. I can connect just fine on my phone’s OpenVPN client so I know the server is set up okay, but the issue is trying to use the same ovpn profile on my Ubuntu 20.04 laptop.
When I try to connect using the OpenVPN client on Ubuntu, I get this:
I tried Googling this, and it seems like the issue here is that the ovpn profile might be using encryption ciphers that aren’t compatible with OpenVPN version 2.4.7, and that the client export tool in pfSense is using OpenVPN 2.5.0.
However, I’m not smart enough on how to set the server up to be compatible with 2.4.7, or edit the ovpn file to be compatible with 2.4.7. I saw a couple of random forum posts that talked about changing the «data-ciphers» line in the ovpn file to add ciphers that are compatible with 2.4.7, but it didn’t work. I don’t remember the site, and I’ve already deleted the file so I don’t remember exactly what they suggested, but it was something along the lines of «data-ciphers AES-128-CBC:AES-128-GCM»
The ovpn file is below:
I’ve also tried to install 2.5.0 on my laptop, but I’m having several issues with that which I won’t go into detail with unless someone thinks it’ll help. The default openvpn version in the Ubuntu 20.04 repo is 2.4.7, so I’m stuck on this for the time being.
Anyone run into this before or know how to fix this?

Hello, I am trying to set up a VPN on my Personal PC using OVPN and have been following this guide :
I got stuck at Part 5B,
After i Edited the client config on the Client PC, and tired to connect, errors that i cannot make sense of occurs, i have followed everything correctly
I am attaching images of the error, the client log and the client config itself.
it says there are unrecognizes or missing or extra params but there is nothing there and im very confused as to where the issue is.
(if you cant see the images, right click and open them in a new tab please)

Post by net.admin » Mon Oct 02, 2017 1:25 pm
This is my first setup that isn’t point to point and I’m receiving the following error which I can’t seem to find the cause of. This is a test on the same network, no routers or firewalls (software included) are in play.
I’m receiving the following error in the log — this is the entire log:
Options error: Unrecognized option or missing or extra parameter(s) in client1.ovpn:10: ca (2.4.4)
Use —help for more information.
Things I’ve tried:
Checked the client / server config’s for obvious error.
Recreate the certificates.
Figure I’m either doing something significantly wrong or missing something. Either way, putting up my hand and asking for a little assistance.

# This will allow Thelonious’ private subnet to
# access the VPN. This example will only work

Hi all,
Trying to set up an OpenVPN connection on pfSense 2.4.5-RELEASE-p1. I am using the SSL-TLS+user auth method. I have a Apple Macbook with Tunnelblick 3.8.4 (build 5600), where I have imported the .ovpn config file generated from the pfSense OpenVPN client conf exporter plugin.
When I try connecting, it fails, with this error:
1606165530.305305 b000 Options error: Unrecognized option or missing or extra parameter(s) in /Library/Application Support/Tunnelblick/Users/will/pcol-gw-wdennis.tblk/Contents/Resources/config.ovpn:4: data-ciphers (2.4.9)
I have set the NCP Algorithms on the pSense server to include all of the AES-* algo’s. The data-ciphers*
lines in the client config are:
data-ciphers AES-128-CFB1:AES-128-CFB8:AES-128-OFB:AES-192-CBC:AES-192-CFB:AES-192-CFB1:AES-192-CFB8:AES-192-OFB:AES-256-CBC:AES-256-CFB:AES-256-CFB1:AES-256-CFB8:AES-256-OFB
data-ciphers-fallback AES-128-CBC
Thanks for any help or info you can provide.
I found that the latest OpenVPN client exporter updates generates OpenVPN 2.5 configs even on pfSense 2.4.5-p1 and when the OpenVPN server is still version 2.4x
I had to check don’t include 2.5 config options
You shouldn’t blindly include all the AES algorithms. Stick to the GCM and CBCs. Most likely explanation is that your client platform doesn’t support one or more of the ciphers.
The client export generates OpenVPN 2.5 configs because it exports OpenVPN 2.5 installers, so that’s probably OK (provided your client platform is running OpenVPN 2.5…)
Your log message does say your client is OpenVPN 2.4.9, though, so you probably do need to update the client to one that uses OpenVPN 2.5.0 or tick the Legacy box and export again.
yea, the error message said,
... config.ovpn:4: data-ciphers (2.4.9)
so I assumed his client was 2.4.9 and not 2.5, but yea, that is a lot of ciphers as well to enable… yea, easiest just to stick GCM/CBC like @jimp said
Thanks for the help, folks!
I upgraded Tunnelblick to 3.8.5beta01 (build 5610), which has OpenVPN 2.5 (also had to set «OpenVPN version» drop in Settings to «Latest», which is OpenVPN 2.5.0 w/ OpenSSL 1.1.1h)
Also edited my client config, it is now:
dev tun

persist-key
data-ciphers AES-128-CBC:AES-192-CBC:AES-192-CFB:AES-192-OFB:AES-256-CBC:AES-256-CFB:AES-256-OFB

Now I do get connected, but I do not have a route to the remote LAN, just one for the VPN network itself (local LAN is 192.168.100.0/24, OVPN network is 192.168.5.0/24, and remote LAN is 192.168.10.0/24):

So it seems I may be missing some needed entries yet on the pfSense (server) side? I made the OVPN config on pfSense via the wizard.
I know its 20 min long these days, but worth a watch and goes over all this settings, including routing to your local network: https://www.youtube.com/watch?v=PgielyUFGeQ
Are you probably missing server settings for IPv4 Local network(s)
and IPv6 Local network(s)
I’m having this problem even with the 2.5.0 client on windows.

the generated ovpn file has
data-ciphers AES-128-GCM
data-ciphers-fallback AES-128-CBC
if I mark the «legacy client» option it changes to
cipher AES-128-CBC
and the client can connect.
It seems the client is ignoring the data-ciphers-fallback option.
Command line pfSense :
openvpn --help
The first line tells you that the latest pfSense (2.5.1) is using
OpenVPN 2.5.1 amd64-portbld-freebsd12.2 [SSL (OpenSSL)] [LZO] [LZ4] [MH/RECVDA] [AEAD] built on Apr 5 2021
I only export settings from pfSense, not the ‘executable Windows OpenVPON Installer package’, I download the latest OpebVPN client from OpenVPN (it’s also open source).
Get it from here : https://openvpn.net/community-downloads/
Like pfSense, don’t stay on «2.5.0». OpenVPN had issues to, so they went to 2.5.1 to stabilised, for now, on 2.5.2.
The 2.5.2 client works fine with the OpenVPN server 2.5.1 on pfSense.
Btw : It’s just pure coincidence that OpenVPN uses nearly identical version numbers as the CE version of pfSense.
@gertjan thank you, but for me and my users the all in one installer is more convenient. I didn’t know that openvpn 2.5.0 had issues.

I just tried with the 2.5.2 openvpn client and it has the same problem:

maybe it’s because I’m still with pfSense 2.4.5p1 that has openvpn 2.4.9 (I cannot upgrade to 2.5.1 due to its problems with NAT and multi WAN)
@olivluca said in Getting error on «data-ciphers» line on OVPN client:
openvpn 2.5.0 had issues.
As pfSEnse, they have a FAQ, manual, forum etc.
Yes, they have issues — like any other huge (OpenVPN is huge ….) (software) product.
The shift from 2.4.x to 2.5.x has special help pages, with all the details about these changes.
If you use OpenVPN, don’t hesistate. Bookmark this one — and use it.

Sure, but I didn’t mean it like that, I was referring to the interaction with the «client export» generated settings. Anyway, the latest release of openvpn has the same problem.
