Ho utilizzato questo comando: "Set-VpnConnectionIPsecConfiguration -Name "Casa" -EncryptionMethod DES3 -IntegrityCheckMethod SHA1 -DHGroup Group2 -AuthenticationTransformConstants SHA1 -CipherTransformConstants DES3 -PfsGroup None" Ottengo questo errore: "ERROR: detected unallowed policy generation injection" "ERROR: failed to generate a proposal template from client's proposal" "[mio indirizzo ip] ERROR: failed to pre-process ph2 packet (side: 1, status: 1)"
L2TP/IPSec VPN not work on Windows 11.
Greetings, sorry for my bad English.
I use a D-Link to use a L2TP IPsec VPN which I configured with:
Phase 1 Settings
Local Peer: Peer1
Negotiation Mode: Main
Identifier Type: Address
IKEv2 Encryption Algorithms: 3DES
Authentication Algorithms: HMAC-SHA1-160
Diffie-Hellman Group: MODP-1024
SA life Time: 86400 seconds
Phase 2 Settings
ESP Encryption Algorithms: 3DES
Authentication Algorithms: HMAC-SHA1-160
Diffie-Hellman Group: MODP-1024
SA life Time: 28800 seconds.
If I try to connect from Windows 11, the log indicates this error:
"ERROR: failed to get valid proposal.
ERROR: no suitable proposal found.
ERROR: invalid DH group 19.
ERROR: invalid DH group 20."
What should I do to remove this error?
Thank you.
