Pfsense Update 2.5.0 - Unrecognized option or missing or extra parameter(s

[kanetoad 1]

Hi Everyone

Installed pfsense 2.5.0 community, no major dramas updating from 2.4.5..

However i'm getting the following error when starting up openvpn.

Feb 17 16:24:49 192.168.10.1 openvpn[53019]: Options error: Unrecognized option or missing or extra parameter(s) in /var/etc/openvpn/client4/config.ovpn:41: key-method (2.5.0)

I'm trying to find out what this parameter may be and if it's specfic to Airvpn, any ideas please?

With no config who should help you?
Do you mean the Extra Option?

Remove anything that isn't actually needed in the custom options, or anything that you didn't actually put there.  I had the same problem and there were lines in custom options that I were not something I put in.

Also, now that pfsense has openvpn 2.5 you might try a switch to chacha20 as "data encryption algorithm" as it might be faster for you than what you were using.

Even on my system that was fast with AES-256-GCM because of AES-NI, chacha20 is for some reason faster.  I think it has more to do with networking and not CPU ease.

I have the same issue. Not able to connect to the servers after upgrade to Pfsense 2.5

Hello!

key-method directive is no more supported in OpenVPN 2.5. Delete it. If you connect with TLS Crypt (entry-IP addresses 3 or 4) you don't need any replacement.

If you connect with TLS Auth, enter the directive:
key-direction 1

Kind regards

Can someone post some screen shot guides on how to configure the latest update on Pfsense 2.5 version, as to how to configure Airvpn ? Please I am unable to understand the above explanation.

Hello

You were right, i had the following custom options in the Advanced config:

client;remote-cert-tls server;persist-key;persist-tun;keysize 256;key-method 2;key-direction 1;explicit-exit-notify 5;mlock;keepalive 5 30;prng sha512 64;

Clearing these out , so my custom =

client;persist-key;persist-tun;remote-cert-tls server;prng sha256 64;mlock;auth-nocache;

Thank you! Edited ... by kanetoad

Yes i'm testing this at the moment, prehaps the preformance gains are hardware specfic, depending on the pfsense socket, intel/amd?

Hello

This was already in my custom option, what's your view on removing these custom options from:

client;remote-cert-tls server;persist-key;persist-tun;keysize 256;key-method 2;key-direction 1;explicit-exit-notify 5;mlock;keepalive 5 30;prng sha512 64;
to...

client;persist-key;persist-tun;remote-cert-tls server;prng sha256 64;mlock;auth-nocache;

AMD64  - CPU usage is flapping around a bit more using the chacha20 ciper.

but there is gains for sure!

This is pretty much my config, pfsense people in these parts will have used the excellent guide at some point for their setup.

kanetoad: Thanks a lot. Your " custom option edit- client;persist-key;persist-tun;remote-cert-tls server;prng sha256 64;mlock;auth-nocache;" has worked.
