Ensure that the authentication algorithm is configured identically on both

that is shared with the IKE peer. Then enter the key in the space provided.
Note that the double-quote character (“) is not supported in the pre-
shared key.
- RSA-Signature— Choose this option to disable the pre-shared key text
field and use the Active Self Certificate that was uploaded on the
Security > SSL Certificate page. A certificate must be configured in
order for RSA-Signature to work.
