When the tunnel is created, the Firebox can use any of these transforms to match the transform set of the other VPN endpoint. You can add more transform sets up to a maximum of nine. For example, you could add SHA1-AES128-DH2. The Firebox would then have four transform sets. The transform set at the top of the list is used first.
A transform set is an acceptable combination of security protocols, algorithms and other settings to apply to IP Security protected traffic, During the IPSec security association negotiation, the peers agree to use a particular transform set when protecting a particular data flow Set-VpnConnectionIPsecConfiguration (vpnclient) Set-Vpn Connection IPsec Configuration. Module: vpnclient. This example sets the IPsec configuration for an IKEv2 tunnel, and specifies authentication transform constants. The first command uses Add-VpnConnection to add a VPN connection on the server with the … CCNA Security v2.0 Chapter 8 Answers - Implementing
We can also use the mode command in crypto transform configuration mode to set the mode for the VPN to be either tunnel (default) or transport (“transport” setting is used only when the traffic to be protected has the same IP addresses as the IPsec peers).
