Define the required fields of VPN:
DES (Data Encryption Standard):
„ The Data Encryption Standard developed by IBM in 1977 is a 64-bit block encryption block
cipher using a 56-bit key.
Triple-DES (3DES):
„ The DES function performed three times with either two or three cryptographic keys.
AES (Advanced Encryption Standard):
„ An encryption algorithm yet to be decided that will be used to replace the aging DES
encryption algorithm and that the NIST hopes will last for the next 20 to 30 years.
Define the required fields of Setting:
VPN IP of Client:
„ Set client and SG-500 establish SSL VPN connection’s authentication account, IP range,
encryption algorithm, protocol, server port, and idle time.
SSL VPN IP range cannot the same with internal (LAN, Multiple Subnet, DMZ), external(WAN), and
PPTP Server’s subnet.
Internal Subnet of Server:
„ The client can be allowed to access internal subnet of server.
