PPTP
Only 128-bit RC4 encryption algorithm is supported.
40 and 56-bit RC4 support is removed, but can be added (not recommended) by changing a registry key.
L2TP/IPsec
Data Encryption Standard (DES) encryption algorithm with Message Digest 5 (MD5) integrity check support is removed, but can be added (not recommended) by changing a registry key.
IKE Main Mode will support:
Advanced Encryption Standard (AES) 256 (new), AES 192 (new), AES 128 (new), and 3DES encryption algorithms.
Secure Hash Algorithm 1 (SHA1) integrity check algorithm.
Diffie-Hellman (DH) groups 19 (new) and 20 (new) for Main Mode negotiation.
IKE Quick Mode will support:
AES 256 (new), AES 192 (new), AES 128 (new), and 3DES encryption algorithms.
SHA1 integrity check algorithm.
