Section 4 - Conguration
IP Subnet Mask:
Enter the subnet mask if you choose Subnet for Remote Access Range.
Pre-Shared Key:
Enter a pre-shared key to authenticate a remote peer. Up to 16
characters including symbols can be entered. Both local and remote
device of the VPN tunnel must use the same pre-shared Key.
Perfect Forward
Secrecy:
Enable or disable Perfect Forward Secrecy. It uses public key
cryptography to improve the security of IPSec data communication.
NAT Traversal:
Enable or disable NAT traversal for the negotiation of an IPSec VPN
connection. It allows IPSec VPN trac to pass if NAT is used on the
gateways.
Key Exchange Phase 1
Exchange Mode:
Select Main, Aggressive or Base. The Main mode sends rst two
messages for negotiating the encryption and authentication method.
In general, Aggressive mode is faster than the Main mode but oers
less protection against authentication security. Unlike the Aggressive
and Main Mode, the Base Mode can transmit the key exchange
information and authentication data together .
Encryption
Algorithm:
Select encryption method as the algorithm for encrypting data
packets. The options are DES, 3DES, AES-128, AES-192 or AES-256.
Authentication
Algorithm:
The authentication algorithm validates data packets. Select MD5,
SHA1, or SHA256. Both local and remote device of the VPN tunnel
must use the same authentication algorithm. Both MD5 and SHA are
one-way hashing algorithm but produce dierent number of digest
bit.
Die-Hellman
Group:
The Die-Hellman key exchange protocol oers dierent prime key
lengths. Select 768, 1024, 1536, 2048, 3072, or 4096 bit.
