OpenVPN Authenticate/Decrypt packet error: packet HMAC authentication
First I want to apologise if this has previously been asked. I have had trouble locating the info required!
I have one pfSense server with local IP 172.16.0.1
1 pfSense clients with local IP-s 172.16.1.1
They are connected together over OpenVPN site-to-site (Shared key, BF-CBC 128 encryption algorithm)
When i setup connection Open VPN tunel works for couple minuts and then it crashes.
Looking at server log i see this massage:
Message: Authenticate/Decrypt packet error: packet HMAC authentication failed
I posted screenshot from server log and client log
How to resolve thiss error
Something between the two does not match. Most likely you didn't copy the shared key from one to the other so they are using different keys.
I'm having the same problem… "Authenticate/Decrypt packet error: packet HMAC authentication failed"
and I've reviewed and re-input the keys a couple of times. I believe this may be related to the recent reset of all of the PIA keys/ports/ciphers due to the Russian activity.
Does anyone have a 'how-to' that includes the most recent changes? TIA.
