Tls error cannot locate hmac in incoming packet from pfsense

Tls error cannot locate hmac in incoming packet from pfsense

Поднял OpenVpn server. Виндовые и прочие клиенты подключаются нормально, все видят сеть и все такое. Есть в удаленной точке Synology NVR, на ней пытаюсь создать подключение ругается что нет сервера или сертификат просрочен. Логи со стороны Pfsense : TLS Error: cannot locate HMAC in incoming packet from [AF_INET6]::ffff:

1. Synology NVR не поддерживает TLS authentication.
или
2. Вы не сконфигурировали на Synology NVR TLS authentication.
На стороне клиента в конфиге это
tls-auth ta.key 1
ta.key — это то, что в pfSense Видно как Key в Cryptographic Settings
или
3. На стороне клиента и сервера не совпадает директива
auth SHA1auth SHA512и т.д.

Я новичок в этих делах можете помочь сконфигурировать конфигурационный файл?

Просто возьмите работающий конфиг с этих клиентов как основу и отредактируйте его применительно к клиенту Synology NVR.

Да пытался что то не получается. Ну что ж бкдк пробовать. В любом случаи спасибо!! 😉

Вот так отредактировал, synology ругается что неверные параметры

Ищите, что конкретно ему не нравится. Добавьте ему в конфиг

И ищите в логе ошибки. У Synology доступен стсемный логлог Open VPN?

Tls error cannot locate hmac in incoming packet from pfsense

Wed Aug 28, 2013 1:57 pm

Hi!
Today i set up Mikrotik device as OpenVPN client for PFSense gateway.
All is ok, but i have one trouble — tls-auth.
When i choose «Enable authentication of TLS packets.» in PFSense, Mikrotik not connecting.
What wrong?

Can you share your settings on Pfsense and mikrotik with just dummy ip address and will try to resolve your problem. we can exchange email : jollyrecto@gmail.com. I have experience on pfsense wiht openvpn but none on mikrotik..

This might come a little late but .

Things that got me up and running(on the microtik hAPs):

1) Import certificate is relatively standard (.crt) I also imported CA, not sure it’s needed.
2) Import key should be done in pem format «openssl rsa -in cert-key.key -out cert-key.pem» + import is necessary not automated, you should see KT in front of cert after successful import.
3) compression(no pref) on pf.
4) tcp not udp.
5) match crypto params AES-128 + SHA1 or anything else.
6) last but not least profile with local + remote IP in PPP menu.

Hope this helps

I have a working Mikrotik to pfSense tunnel via OpenVPN working. This is not a full guide but here are some steps to help you:

You must set up the VPN server on pfSense’s side using the «Remote Access (User Auth)» Server Mode. The reason for this is that Mikrotik requires usernames/passwords for OpenVPN operation. So you will need to add VPN users to pfSense’s side and use the login(s) from the Mikrotik device. Im not going to cover SSL + User Auth as that will just add complexity right now.

TLS authentication (Static keys) is not supported in RouterOS right now. Unfortuantely this restricts from being able to use the peer-to-peer modes directly You need to ensure the «Enable authentication of TLS packets» is unchecked on pfSense.

Due to constraints in this mode, you must use /29 for your ipv4 tunnel network. Make sure you check «Allocate only one IP per client» in the topology section

You will need to ensure the CA cert generated (if one doesnt exist you will need it for Remote Access mode) is imported into your Mikrotik device. Note, you do NOT set this as the certificate in the Mikrotik OpenVPN client interface

Disk Full: TLS Error: cannot locate HMAC in incoming packet from.

Post by dsetis » Thu Jun 21, 2018 11:14 am

Sometimes I have received attempts to connect to my server (not real connections I think), and each one of them, generating entries in my LOGFILE:
«TLS Error: cannot locate HMAC in incoming packet from. »
Result: 20G logfiles per day, that my rotate can’t manage..
What is the best way to solve it?

— «verb 0» isn’t a good option, i think.
— «disable the TLS security?» wrong way .

Any ideas?

With «0», I think no LOGS will be generated and its not so good.
with 1, the LOG is usefull, the problem is about the TLS attack. With 1, its flooding openvpn.log file

I was really confused.
I’m so sorry

I reversed mute option. 2 = less equals logs.
Thanks. Its working!

pfsense as openvpn client

Orddie

I have been using openvpn server on a Linux host and connecting to that server from a windows host and bridging the connections together.

I tried configuring pfsense to replace the windows 7 box but it does not appear to be working correctly.

From the logs on the linux box. It would appear that pfsense is NOT making any attempt to connect to the Linux server.

Does anyone have suggestions where i can start?

I can not see pfsense trying to talk to the openvpn server.

I’m getting the following in the openvpn server log
TLS Error: reading acknowledgement record from packet
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

and the following in the pfsense openvpn log
TLS Error: cannot locate HMAC in incoming packet from [AF_INET]XX.XXX.XXX.XXX:1194 (replaced ip w/ X’s)

Shockey

after googling the error you get from pfsense. i got this link

says to do this

i have no idea what that means.

the server is the linux box. the client is the pfsense box.

Orddie

okay. got it up and «working» now.

The connection appears to be connected but i can not ping the other network. I have done an iptables —flush on the linux box and did an allow any any in pfsense openvpn port.

any suggestions where to go from here?

I added 192.168.1.0/24 to route over the opt1 interface.

The interface; once connected got an ip of 192.168.1.2 with a default route of 192.168.1.1 (the interface on the linux server).

I could never ping 192.168.1.2 from the linux server and could never ping 192.168.1.1 from my home network.

I could ping 192.168.1.2 (interface on pfsense server) from my home network.

@ times when the openvpn connection started up. It would kill all of my internet connection. According to the logs it looks as if it changed the default route to force
everything over the openvpn connection. That’s not my goal here. I’m looking to extend the network to be able to route traffic «internally».

I ended up moving the connection to the exchange server and bridging the tap interface with the servers network card. It’s not how i wanted it. I still want pfsense to handle this but after 6 hours of working on it. I needed to move on.

tls-auth in openvpn.conf not working #14

when i disable the line # tls-auth /etc/openvpn/pki/ta.key it works.

The text was updated successfully, but these errors were encountered:

Sounds like your client is misconfigured and not sending HMAC signatures.

Funny error on my mint linux, when i use the ovpn-file and connect manually openvpn my.ovpn it work.
When i import the same ovpn-file in the network manager, i can’t connect.

So it is no issue of docker-openvpn (tested also with win7, ubuntu 12.04 LTS, OSX and it works fine).

Thanks for the update. Glad to hear you got it working.

I assume Network Manager is messing with your config file. That «tool». haha. 😉

Sorry to bump an old topic, but if anyone find the same issue, you’re probably missing to configure your TLS auth key in the (graphical) network manager. First I split the client.ovpn file into several ones (client.crt, ca.crt, client.key. and ta.key (with what is in between )). While configuring your connection, you need to click on «Advanced» > TLS Authentication tab. Check the «Use additional TLS authentication», select your file (ta.key or whatever you call it) and «1» as key direction. Click Ok and you’re done.

I have to install openvpn server on debain after configuration and creation of clients I made the test on the server by executing the command openvpn client.ovpn it sends me this message of errors someone can help me please

Tue Mar 7 14:12:42 2017 TLS Error: cannot locate HMAC in incoming packet from [ AF_INET]154.65.33.243:49816

I’m also having the issue, even with the

Check the «Use additional TLS authentication», select your file (ta.key or whatever you call it) and «1» as key direction

Or also with pure openvpn cli: openvpn —config my.ovpn

What can I disable to verify the rest is working properly?
