L2TP IPSEC - Disable or change Dynamic IPSec Rule

Hello,

i have created a L2TP connection with IPSEC enabled.

But i need Sha256 and the dynamic created IPSEC rule only supports Sha1. I can create a new rule and delete the dynamic rule. All works find, but on reboot the dynamicrule is created again.

Is there a way to change the default rule or prevent its autocreation ?

No. When the default rule is not good for you, you need to remove the IPsec setting from L2TP and do it all by yourself.
