public networking infrastructure.

Remote:
•
Remote Gateway IP: The IP address of the remote VPN device that is connected and
establishes a VPN tunnel.
•
Remote Subnet/Network: Set the IP address, subnet or address range of the remote network.
Proposal:
•
Proposal: Select the IPSec security method. There are two methods of checking the
authentication information, AH (authentication header) and ESP (Encapsulating Security
Payload). Use ESP for greater security so that data will be encrypted and authenticated.
Using AH data will be authenticated but not encrypted.
•
Authentication: Authentication establishes the integrity of the datagram and ensures it is not
tampered with in transmit. There are three options, Message Digest 5 ( MD5 ), Secure Hash
Algorithm ( SHA-1 ) or NONE . SHA-1 is more resistant to brute-force attacks than MD5,
however it is slower.
•
MD5: A one-way hashing algorithm that produces a 128-bit hash.
•
SHA-1: A one-way hashing algorithm that produces a 160-bit hash.
•
Encryption: Select the encryption method from the pull-down menu. There are four options,
DES, 3DES and Without Encryption. Without Encryption means it is a tunnel only with no
encryption. 3DES is more powerful but increase latency.
•
DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method.
