ok sounds like you know why ask.wink
but in short, sha2 consists of SHA-256, SHA-384, SHA-512

but on ER605 I recomand SHA-256

Hi @ZIZOU94 

Thanks for posting in our business forum.

Our senior member MR.S gave some very helpful insight and comments.

For a standard IPsec, in the IKE, you have three options to be filled.

 

SHA: Responsible for data integrity and authentication.

AES: Responsible for data encryption and decryption, ensuring communication confidentiality.

DH: Responsible for key exchange, ensuring both parties can securely generate a shared key.

 

You miss the DH group which should be specified before it starts to work.

Port forwarding is necessary as well if you set up IPsec S2S.

I don't know what you have on the other end of the vpn but SHA2-256 SHA-256 should be the same. but there are many other parameters in a VPN tunnel that must match for it to work.
