Phase 2 Authentication: There are two methods of authentication, MD5 and SHA. The Authentication method
determines a method to authenticate the ESP packets. Both sides must use the same Authentication method.
MD5 is a one-way hashing algorithm that produces a 128-bit digest. If users enable the AH Hash Algorithm in
Advanced, then it is recommended to select Null to disable authenticating ESP packets in Phase 2, but both sides
of the tunnel must use the same setting.
Phase 2 SA Life Time: This field allows you to configure the length of time a VPN tunnel is active. The default
value is 3,600 seconds.
Preshared Key: Character and hexadecimal values are acceptable in this field, e.g. “My_@123” or
“4d795f40313233.” The max entry of this field is 30-digit. Both sides must use the same Pre-shared Key. It’s
recommended to change Preshared keys regularly to maximize VPN security.
