IPSec Connections using Remote User Access

Access as a Connection Type, enter the following values:

■ Connection Name — Enter a descriptive name for the

connection.

■ Remote User ID — Enter the Remote User ID. This must be

entered identically on the IPSec software installed on the

client’s machine.

■ Tunnel Shared Key — this is the password for the connection

and is a combination of letters, numbers and punctuation and

can be up to 64 characters in length.

■ Encryption type — choose the encryption type from DES,

3DES or AES. 3DES is more secure than DES but may take

longer to encrypt and decrypt. AES provides the highest

security but will take longer than 3DES to encrypt and

decrypt.

3DES and AES are not shipped with the Router as standard due

to international restrictions on encryption. If your country permits

their use they can be downloaded from the 3Com web site at

http://www.3com.com/

■ Exchange keys using — choose the encryption method used

to exchange shared keys. Diffie-Hellman Group 5 and

Diffie-Hellman Group 2 are more secure but less common

than Diffie-Hellman Group 1.

■ Use Perfect Forward Secrecy — Choose whether to use

perfect forward secrecy. Using perfect forward secrecy will

change the encryption keys during the course of a connection
