2.6 cant get openvpn working

JKnott

Your problem appears to be different from mine.

Honeybadger

@gertjan i know, why i have a bridge.

Still, any idea why I can't get openvpn working?

Gertjan

@honeybadger said in 2.6 cant get openvpn working:

write UDPv6: Can't assign requested address (code=49)
.... [AF_INET6]::ffff:192.168.1.178:51280 (via ::ffff:184.103.180.206%bridge0) ...

I have :

UDPv4 link local (bound): [AF_INET]192.168.10.3:1194

that is : I use IPv4.
I've nothing against IPv6 .... but try making IPv4 working first.

As you can see, v4. Ideas?

Gertjan

@honeybadger

You could do what is advised :

see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings

And if your not using IPv6 : why :

write UDPv6: Can't assign requested address (code=49)

Can you detail your OpenVPN server settings ?
Your WAN is a normal interface - no VLAN, of whatever this " %bridge0) " is.
What for device are you using ?

@honeybadger said in 2.6 cant get openvpn working:

TLS Error: cannot locate HMAC in incoming packet from

Google this one. I find, for example : How to fix OpenVPN “TLS Error: cannot locate HMAC in incoming packet from …” which says to me that the client config used doesn't correspond with what you exported in the pfSense GUI.

Honeybadger

@gertjan i followed these instructions: https://www.informaticar.net/how-to-setup-openvpn-on-pfsense/

I thought I set your advisments. Thanks for your time.

Gertjan

@honeybadger said in 2.6 cant get openvpn working:

https://www.informaticar.net/how-to-setup-openvpn-on-pfsense/

You can use https://what-ever-I-can-find-on-the-internet.tld but why wouldn't you also use these sources :

Docs » pfSense software » Virtual Private Networks

This video "a working OpenVPN in 5 minutes", made by the ones who build pfSense.
Configuring OpenVPN Remote Access in pfSense Software
Actually, all the OpenVPN video @Youtube -> Netgate, even the ones that are x years old are very important as they show examples.

If you really used a documentation, based on a very old pfSense version and also old OpenVPN (2.3.x or even before ?), it's a 100 %chance that things won't work out.
OpenVPN is security related so there are important changes a couple of times each year.

Normally, I build a "as per author instructions" setup, and this if everything works.
Every error or warning shown in the logs have to be considered as show stoppers until, from official source, they can be allowed.
Then, and only then, I add my own personnel settings, options and I test them one by one.

Honeybadger

@gertjan i read through your recommendated docs and videos.

I dont see the difference btween my install docs and yours, please point out the missing steps/data?

Thanks

Gertjan

@honeybadger said in 2.6 cant get openvpn working:

see the difference btween my install docs and yours

I'm not using or referring 'foreign' sources, as I only use the originals.
If there are differences, as you use older documentation, that's up to you to find them ;)

Honeybadger

@gertjan i did follow your recommended instruction at pfsense, ended with the same problem. I couldn't find anything different in setup between my original and your instructions.

Gertjan

@honeybadger said in 2.6 cant get openvpn working:

same problem

You mean : you used Configuring OpenVPN Remote Access in pfSense Software and the instructions in that video didn't work right away ?

There are some requirements that are not mentioned :

The latest pfSense version.
Default pfSense setup (no fancy routing, no VLAN, no other packages except the pfSEnse "openvpn-client-export" package.
A OpenVPN client version that uses 2.5.x (pfSense 2.6.0 is using OenVPN 2.5.4)

Anyway, I'm curious now. I"ll blow away my settings @home - reboot to default, assign interfaces, change the password and stop there. I'll play back the video.
I'll be using this client OpenVPN Connect Phone or PC version.

Since Mars 2020, thousands are using OpenVPN as we all had to work from home.

Honeybadger

@gertjan excellent!

Thankyou for your time!

I look forward to your reply!

Thank you thank you thank you!

Help please?

On the way - as soon as I get @home, i'll do a test setup.

Your are testing with 2 IP's on the same network. 192.168.1.178 to 192.168.1.172, I've never tested that, and if it would connect, it would probably still fail.
The situation should be : an openvpn server listening on the WAN port. This WAN port could be RFC1918 and you could have an upstream "ISP" router with the "UDP 1194" port natted to pfSense.
Use your phone with the data carrier (3G/4G/LTE/...) , not the Wifi (!) so it use an arbitrary 'outside' IP, not some local RFC1918.

And again :

openvpn TLS Error: cannot locate HMAC in incoming packet from

shows many examples saying just one thing : HMAC on server and client are not the same.

Also : Your OpenCVPN server version is 2.5.4 - what are you using as a client - and what version ?

Just to be sure : check your NTP setup on all devices. Time should be the same, like within a second or so.

Post your openvpn server config file ( Folder /var/etc/openvpn/server1 - the config.opvn file)

How did you create the client config file ?
No client override instruction ? ( here : VPN > OpenVPN > Client Specific Overrides )

What have you checked on the VPN > OpenVPN > Client Export Utility page ?

@gertjan i created with the openvpn export wizard.

Latest android openvpn client and latest open wizard verson 1.6_4.

My pfsense is 2.6.0
Android client is 3.2.5(7182)
I looked in /var/etc/openvpn/server1 butdont see a config file. (ovpn)
No overrides

Thanks for the help

Gertjan

@honeybadger said in 2.6 cant get openvpn working:

I looked in /var/etc/openvpn/server1 butdont see a config file. (ovpn)

or server2 - or 3 etc - depedning on the number of openvpn servers you have (had) set up :

a config.ovpn file must exist, otherwise the openvpn server can't run.

I've just created my home openvpn server according to the Netgate video.

My tunnel network is 192.168.80.0/24
I use only IPv4.

What I did that not in the video :
I had to port NAT my ISP router : port 1194 UDP => to my pfSense.
I assigned a OpenVPNserver as an interface :

and I moved the Wizard generated firewall rule from the OpenVPN to the new OPENVPNSERVER tab :

I opened the resolver settings page, saw that in the incoming and outgoing connections my new OPENVPNSERVER was listed among the others.
I restarted the Resolver - now it also listens on the OpenVPN network.

I also visited Services > NTP > Settings and added OPENVPNSERVER to the "Interfaces" box so my openvpn clients can connect a NTP source.

I don't use "User auth", but TLS only, so without user/password :

so I added a user called 'vpn' with a cert based on the OpenVPN server cert :

(on the user Manager page : )

I installed the OpenVPN export package, and saw my openvpn user 'vpn' listed :

Exported (dwonloaded) the "OpenVPN Connect (OS/Android) openvpn client config file.

Mailed the client config myself, imported it into my iPhone.

I also double checked that the DDNS URL that points to my WAN IP is correct.

I connected just fine.
No errors in the OpenVPN server log, except the two classic wartnings :

WARNING: 'keysize' is used inconsistently, local='keysize 256', remote='keysize 128'
WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1569', remote='link-mtu 1553'

No issues on the client side.
I could visit the pfSense WebGUI, and visit any other web server on my LAN (10.0.0.0/24) and whatever Internet site, like https://forum.netgate.com.

Extra OpenVPN server settings :

As said earlier, I use the OpenCONNECT app ( made by the OpenVPN authors).
Its compatible with the OpenServer code pfSense uses (version 2.5.4).

I did not see time or 'replay' issues, neither HMAC errors.

I de activated the Wifi on my phone, so I was really accessing the OpenVPN server from the Internet.

@gertjan not meaning to argue. In my /var/etc/openvpn/server1 (only server1 exists) are the directories csc and ca and that is it. I am running pfsense on a Netgate 2440 appliance. Maybe 2.6 didn't install properly? It said it did but it's not been able to run openvpn since upgrading.

You're alot more nuts and bolts aware than me.

Last time i set up openvpn, about 2.4 pfsense version. All i had to do was go to vpn/openvpn/wizards, set up server cert, go to user manager and set up a client with user cert and use the export too to send a archive of the 3 files to myphone, tablet, or laptop and if just worked, took about 10 mins.

Can't get it working now.

The config.ovpn was missibg because i deleted everything, i went though and reinstalled (wizard methodl.

Here's my fresh config.ovpn file:

Now when i try to export I get: Could not locate the CA reference for the server certificate.

I checked my server cert is openvpn_ca.

Looks right in server and client setups

@honeybadger said in 2.6 cant get openvpn working:

Something is running, as you showed the log.
You use a Netgate appliance, not me. Normally, that shouldn't differ - but doesn't your pfSense ( should ?) uses something like pfSense 22.x ?

Open a console or SSH access and run :
ps ax | grep openvpn
You'll see a line like :

4000  -  Ss      0:00.33 /usr/local/sbin/openvpn --config /var/etc/openvpn/server1/config.ovpn

That's a way to determine where the config file is located.

Left is my config file - right is yours :

The first line :
I have dev ovpns1, you doesn't have 'dev' in front - - not important ?
The 'local' is ok, these are our WAN IPs - not important
I have the AES-NI Intel engine activate - not important
My tunnel network is 192.168.80.0/24 - yours is 192.168.200.0/24 - that's ok.
The TLS-verify are identical except the CA cert name : strange : Mine use the OpenVPN server cert from the Certificate page. Do you use somehow ( ? ) the cert from the CA (first) page ?

I have this :

Where "CA OpenVPN server" is on the CA page.
Server certificate, I called it "OpenVPN server" is on the Certificate page.

You limit the number of clients, i don't - not important
I have checked :

so that explains my "push "redirect-gateway def1"
I don't push routes - probably not important.
On the other hand, I push a lot of other image, as said above - - not important - that said, pushing a working DNS, our Resolver, 10.0.0.1 is my LAN, seems important to me.
I could also be using 192.168.80.1 as I instantiated the OpenVPN interface and now the resolver is also listening on 192.168.80.1.
dh /etc/dh-parameters.2048 or 4096 -not important

Btw : I don't know what this is :

username-as-common-name
plugin /usr/local/lib/openvpn/plugins/openvpn-plugin-auth-script.so /usr/local/sbin/ovpn_auth_verify_async user TG9jYWwgRGF0YWJhc2U= false server1 1194

Is that the extra stuff we have if we use a Netgate device ? Dono.

What I think : the issue is your on the client side the app used.

@honeybadger said in 2.6 cant get openvpn working:

Now when i try to export I get: Could not locate the CA reference for the server certificate.
Failed to export config files!.

How is that shown ? Where ?

Btw : you better remove your WAN IP in your message.
