MAC addresses are  entered  in [Exception  Addresses].  Communications with other devices are
permitted.
2Specify  address exceptions.
Enter the  MAC address in the  [Address to  Register] text box and  click [Add].
You  do not  need to  delimit  the  address with hyphens or colons.
IMPORTANT:
Check for entry errors
If  MAC addresses are  incorrectly entered, you may  become unable to  access the  machine from the  Remote  UI, in which
case  you need to  set  to  .

Changing Port Numbers
Ports  serve as endpoints for  communicating with other devices.  Typically, conventional port numbers  are  used for  major protocols,  but
devices that  use these port numbers  are  vulnerable  to  attacks  because  these port numbers  are  well-known. To enhance security,  your
Network Administrator may  change the  port numbers. When  a port number has been changed, the  new number must be shared  with the
communicating devices,  such as computers and  servers. Specify the  port number settings depending on  the  network environment.
NOTE
To change the  port number for  proxy server, see  Setting a Proxy.
To change the  port number for  LDAP server, see  
Registering LDAP Servers (MF8580Cdw  / MF8550Cdn / MF8540Cdn /

Setting a Proxy
A proxy (or HTTP proxy server) refers to  a computer  or software  that  carries out  HTTP communication for  other devices,  especially  when
communicating with resources  outside the  network, such as when browsing Web sites. The client  devices connect to  the  outside ne twork
through the  proxy server, and  do not  communicate directly  to  the  resources  outside.  Setting a proxy not  only facilitates manage ment  of
traffic between  in-house and  outside networks but also  blocks unauthorized access and  consolidates  anti-virus protection for  en hanced
security.  When  you use Google  Cloud Print  to  print over the  Internet, you can enhance security by setting a proxy. When  setting a proxy,
make sure  that  you have the  necessary  proxy information, including the  IP  address, port number,  and  a user  name and  password fo r
authentication.
Start  the Remote UI  and  log  on in System Manager Mode.  Starting Remote UI
Click [Settings/Registration].
Click [Network Settings]  [TCP/IP  Settings].
Click [Edit...] in [Proxy Settings].
Select the [Use Proxy] check  box and  specify the required settings.

Enter the  address of the  proxy server. Specify the  IP  address or host  name depending on  the  environment.
[HTTP  Proxy  Server Port Number]
Change  the  port number as necessary. Enter a number between  1  and  65535.
[Use Proxy  Authentication]
To enable  authentication by the  proxy server, select the  check  box and  enter up  to  24 alphanumeric  characters  for  the  user  name
in the  [User Name] text box.
[Set/Change  Password]
To set or change the  password for  the  proxy authentication,  when it is  enabled,  select the  check  box and  enter up  to  24
alphanumeric  characters  for  the  new password in the  [Password]  text box.
Click [OK].

Restricting the Machines Functions
Some  of the  functions of the  machine may  rarely be used or provide opportunities for  misuse. For security purposes, the  machine can be
set to  limit its capabilities by partially or completely disabling these functions.

Restricting Access to Address Book and Sending Functions (MF8580Cdw /
MF8550Cdn / MF8540Cdn / MF8280Cw Only)
Some  cases of information  leakage can be prevented  by limiting the  available fax  and  e-mail destinations to  those registered in the
Address Book or LDAP servers, or by setting a PIN  for  the  Address Book so that  unauthorized users  cannot  add  or edit Address Book
entries. You  can also  avoid  sending documents to  unintended  recipients  if  the  machine is  set to  ask  you to  enter the  fax  number twice
for  confirmation.

Setting a PIN for Address Book
The Address Book can be set to  require users  to  enter a PIN  in order to  add  new entries to  the  Address Book
or edit existing entries. Setting a PIN  to  the  Address Book can reduce  the  risk of documents being sent to
unintended  recipients  because  changes to  the  Address Book can only be made  by users  who know the  PIN.
Press  .
Use  / to select ,  and  press  .
If  the  logon screen appears, enter the  correct ID and  PIN  using the  numeric keys, and  then  press .Logging  on  to the
Machine
Select    .
Set the PIN for editing the Address Book.
Enter a number of up  to  seven  digits  using numeric keys, and  press .
When   is  displayed,  enter the  PIN  once again to  confirm.
NOTE:
You  cannot  set a PIN  that  consists only of zeros, such as "00" or "0000000".
To disable the  PIN, press 
to  erase the  PIN  (leave the  text box blank),  and  press .
Press  .
NOTE
In addition to  setting the  Address Book PIN, you can further enhance security by performing the  following  operations:

Limiting Available Destinations
By limiting fax  numbers  that  can be specified when sending documents to  those already  registered in the
Address Book,  those previously used, or those searchable  from the  LDAP servers, you can reduce  the
possibility of specifying  incorrect  destinations and  prevent  users  from leaking information. When  this function
is  enabled,  the  machine prohibits users  from entering  destinations using the  numeric keys, adding new entries
to  the  Address Book,  and  editing the  existing Address Book entries.
Press  .
Use  / to select ,  and  press  .
If  the  logon screen appears, enter the  correct ID and  PIN  using the  numeric keys, and  then  press .Logging  on  to the
Machine
Select  .
Select ,  and  press  .

Cancels the  restriction on  new destinations. Fax numbers  and  e-mail addresses can be specified by using any method.

Enables the  restriction. Users need to  specify  destinations by selecting from the  Address Book or searching the  LDAP servers.
