2. Aggressive Mode There are two types of Phase 1 exchanges Main mode and Aggressive mode Aggressive Mode requires half of the main mode messages to be exchanged in Phase 1 of the SA exchange If network security is preferred select Main mode When users select the Dynamic IP in Remote Security Gateway Type it will be limited as Aggressive Mode Compress Support IP Payload compression Protocol IP Comp The Router supports IP Payload Compression Protocol IP Payload Compression is a protocol to reduce the size of IP datagrams If Compress is enabled the Router will propose compression when initiating a connection If the responders reject this propose the Router will not implement the compression When the Router works as a responder the Router will always accept compression even without enabling compression Keep Alive This mechanism helps to keep up the connection of IPSec tunnels Whenever a connection is dropped and detected it will be re established immediately AH Hash Algorithm AH Authentication Header protocol describe the packet format and the default standards for packet structure With the use of AH as the security protocol protected is extended forward into IP header to verify the integrity of the entire packet by use of portions of the original IP header in the hashing process There 45 10 100 8 Port VPN Router are two algorithms MD5 and SHA1 MD5 produces a 128 bit digest to authenticate packet data and SHA1 pro
3. Encryption There are two methods of encryption DES and 3DES The Encryption method determines the length of the key used to encrypt decrypt ESP packets DES is 56 bit encryption and 3DES is 168 bit encryption 3DES is recommended because it is more secure and both sides must use the same Encryption method Authentication There are two methods of authentication MD5 and SHA The Authentication method determines a method to authenticate the ESP packets MD5 is a one way hashing algorithm that produces a 128 bit digest SHA is a one way hashing algorithm that produces a 160 bit digest SHA is recommended because it is more secure and both sides must use the same Authentication method Encryption Key This field specifies a key used to encrypt and decrypt IP traffic and the Encryption Key is generated yourself The hexadecimal value is acceptable in this field Both sides must use the same Encryption Key If DES is selected the Encryption Key is 16 bit If users do not fill up to 16 bit this field will be filled up to 16 bit automatically by 0 If 3DES is selected the Encryption Key is 48 bit If users do not fill up to 48 bit this field will be filled up to 48 bit automatically by 0 Authentication Key This field specifies a key used to authenticate IP traffic and the Authentication Key is generated yourself The hexadecimal value is acceptable in this field Both sides must use the same Authentication key If MD5 is selected the Authenticatio
