cipher AES-256-CBC

check the latest screenshot i have added after you wrote

Where in your config is your ncp ciphers?

ncp-ciphers AES-128-GCM:AES-192-GCM:AES-256-GCM:AES-128-CBC:AES-192-CBC:AES-256-CBC

@johnpoz
that's the point

johnpoz

So your saying that option is missing to set in the gui in 2.5?

Oh your drawing all snipped up - I use faststone which has an autoscroller for taking long screens.

kiokoman

it is available in the GUI but not saved inside the config

johnpoz

I get ya now - hmmm... I don't currently have 2.5 to fire up..

For clarity besides saying lastest, you should always list the exact version your using even if saying latest.. That goes for anything firmware, software, etc.. You might want to add that.. Lets see if I can fire up a 2.5 snap to test with.

There you go, much better ;) just 1 picture. heheh

I looked I had purged the 2.5 vm I was playing with - have to reset it up to try and duplicate..

johnpoz

Ok - VM is up, I can try and duplicate.. But your not on the "latest"

Nov 9 build is out..

faststone:

Firefox can do that too.

johnpoz

Ok - your setup as shared key.. So yeah ncp would be disabled anyway.

Do you really have a shared key setup? That was working before.. I can fire up another 2.5 vm..

Maybe it's an update to OpenVPN 2.5? I checked the changelog/release log a while ago and there were quite a few changes to NCP etc.?

johnpoz

Well having a bit of problem setting up my lab..

Tried to add some vlans to my 2 vms, so could route those networks over the shared key vpn.. And both are crashing with this..

kiokoman

it was working without any problem before the upgrade to the latest snapshot

Already being worked on: #10919
https://redmine.pfsense.org/issues/10919

JeGr

Yep, as I thought, that's one of the new 2.5-series changes to handling ciphers and now "defaulting" to use ciphers alternative/additional to ncp-ciphers (that are to be renamed) etc. I saw quite a few small changes to config files that way. And I'm still not sure why the hell I should provide multiple ciphers via NCP or with ciphers: (now), if I control the server and roll out the clients. Just define a good working set like AES-256-GCM, SHA256, ECDH only with secp384r1 and be done with it. Bit annoying but once the UI will deal with it - not that much of my problem anymore. ;)

This should be all good now. It'll be in snapshots later today, or you can gitsync from a snapshot with the problem to pick up the fix.

It primarily affected shared key instances. When I was testing on Friday before I committed the changes that broke it, I was primarily focused on SSL/TLS configurations and didn't spot that shared key would have ended up with nothing.

Though also from the looks of it, the Data Ciphers (formerly known as NCP ciphers) may not have been working with shared key even before this.

But it should be all good now on 2.5.0.

kiokoman

yes, it's ok now
