How to disable PFS

How do I switch off perfect forward security for a site to site IPSec VPN?

There is no tickbox on the policy settings page. This means I cannot connect to Microsoft Azure.

  • Edit your IPSec policy and set the PFS Group in Phase 2 to None. That will disable PFS, at least when looking at the IPsec Policies.. I hope it will help you out
