l2tp muvpn with certificate
I'm trying to understand how we can to authenticate muvpn with l2tp users with a certificate.
We already use l2tp muvpn with psk and we wish to switch to l2tp with certificate. I've read the guide but it's not clear how to realize this configuration:
Is it mandatory to have a management server and the firewall must be a managed device?
can we use a wild card third party certificate (bought from godaddy)?
alternatively can we use a certificate signed by internal CA authority (microsoft) making a CSR made by firebox?
anyone can clarify this?
