z

  AES:  Stands for Advanced Encryption Standards, you can use 128, 192 or 256 bits as 

encryption method.

 

 

~

 

It is a Message Digest algorithm which coverts any length of a message 

into a unique set of bits.  It is widely used MD5 (Message Digest) and SHA (Secure Hash Algorithm) 
algorithms. 

SHA is more resistant to brute-force attacks than MD5, however it is slower. 

z

 

A one-way hashing algorithm that produces a 128−bit hash. 

z

 

A one-way hashing algorithm that produces a 160−bit hash.

  (Diffie-Hellman key length)

 

It is a public-key cryptography protocol that 

allows two parties to establish a shared secret over an unsecured communication channel (i.e. over 
the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP 
stands for Modular Exponentiation Groups.

If checked, the VPN Client will activate Config-Mode for this tunnel. 

Config-Mode allows to the VPN Client to fetch some VPN Configuration information from 
the VPN gateway like DNS/WINS server IP addresses. In case Config-Mode is not 
available on the remote gateway, please refer to section “Phase2 Advanced” settings to 
manually set DNS/WINS server addresses.
