IPv6 Address

The IPv6 address for the range, or *ALL, representing all addresses that are not otherwise listed.

Address prefix length

Incoming terminal name

The terminal sending the request. This can be a single name, a generic* name, *ALL, or *BLANKS. For a list of known terminal names, press the F4 key.

Minimum pwd validation

The minimum password validation level needed for the logon. The possibilities include:

  • 0: No password
  • 1: With password
  • 2: Encrypted password
  • 3: SSL connection

 

Time group

If set, Telnet connections from this IPv6 range can only be made during the times defined for this time group (as shown in Defining Time Groups).

Logon

How Firewall responds to the logon request. The possibilities include:

  • 1: *ACCEPT: Accept logon request
  • 2: *REJECT: Reject logon request
  • 3: *AUTOSIGNON: Sign on automatically if permitted by system configuration
  • 4: *FRCSIGNON: Force the user to sign on even if the system is configured to accept an automatic signon.
  • 5: *ACCEPTSIP: Accept logon request if it is from the same IP as your system.

Assign terminal name

The name assigned to the terminal if the logon is accepted. This can be an exact name, a generic* name, *SAME, or *SYSTEM.
