through to 192.168.1.254).

Proposal:
Proposal: Select the IPSec security method. There are two methods of checking the

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
