Compatibility between aes-cbc-256 and aes-gcm-256 encryption.
I need configure a VPN IPsec between a pfSense 2.4.5 and other Remote Firewall.
The Admin from the Remote Site tell me that the Remote Firewall has configured aes-cbc-256 encryption but my pfSense 2.4.5 hasn't this encryption type.
would It work if I configure aes-gcm-256 in my pfSense to connect to the Remote Firewall that has configured aes-cbc-256 encryption?
The two are different, they can't work together. But you do have AES 256 on pfSense in IPsec. Select AES with a key length of 256.
@jimp, thanks so much by your answer.
Then if I configure in my pfSense:
Key length: 256
It can connect with the Remote Firewall that has configured aes-cbc-256 encryption?
Yes, that is the same encryption.
Thanks so much.
