Connection Name:
A user-defined name for the connection (e.g. “connection to office”).
Local:
Network:
Set the IP address, subnet or address range of the local network.
Single Address:
The IP address of the local host.
Subnet:
The subnet of the local network. For example, IP: 192.168.1.0 with netmask
255.255.255.0 specifies one class C subnet starting from 192.168.1.1 (i.e. 192.168.1.1

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 (SHA1) or NONE. SHA1 is more resistant to brute-force attacks than MD5, however
it is slower.
