Enabling SSL Encrypted Communication for the Remote UI
You  can encrypt  communication between  the  machine and  a Web browser  on  the  computer  by using Secure Sockets Layer  (SSL). SSL  is
a mechanism for  encrypting  data sent or received over the  network. SSL  must be enabled  when the  Remote  UI is  used for  specifying
settings for  IPSec (Pre -Shared  Key Method), IEEE  802.1X authentication (TTLS/PEAP), or SNMPv3.  To use SSL  for  the  Remote  UI, you
need to  set a key  pair  and  enable  the  SSL  function.  Generate  or install the  key  pair  for  SSL  before enabling  SSL  (

Click [Settings/Registration].
Click [Network Settings]  [TCP/IP  Settings].
Click [Key and  Certificate...]  in [SSL Settings].
Click [Register Default Key] on the right of the key pair you want to use.

If  you try to  start the  Remote  UI when SSL  is  enabled,  a security alert may  be displayed regarding the  security certificate.  In this
case, check  that  the  correct URL is  entered  in the  address field,  and  then  proceed to  display the  Remote  UI screen. Starting

Enabling  SSL for e-mailing  (MF8580Cdw / MF8550Cdn  / MF8540Cdn  only)
If  the  SMTP server  and  the  POP3  server  support SSL, you can enable  SSL  for  communication with these servers (Configuring
Advanced E- mail  Settings ). For more information  about  the  SMTP server  and  the  POP3  server, contact your Internet  service
provider  or Network Administrator.

Configuring IPSec Settings
Internet  Protocol Security (IPSec or IPsec) is  a protocol suite for  encrypting  data transported over a network, including Internet  networks.
While SSL  only encrypts data used on  a specific application,  such as a Web browser  or an  e-mail application,  IPSec encrypts either whole
IP  packets  or the  payloads of IP  packets, offering  a more versatile security system. The IPSec of the  machine works in transport  mode,
in which the  payloads of IP  packets  are  encrypted. With this feature, the  machine can connect directly  to  a computer  that  is  in the  same
virtual private network (VPN). Check the  system requirements and  set the  necessary  configuration on  the  computer  before you configure
the  machine.
System Requirements
NOTE
IPSec functional restrictions
IPSec supports communication to  a unicast address (or a single device).
The machine cannot  use both  IPSec and  DHCPv6 at the  same time.
IPSec is  unavailable  in networks in which NAT or IP  masquerade is  implemented.
Using  IPSec with IP address filter
IP  address filter  settings are  applied before the  IPSec policies.
Specifying IP Addresses  for Firewall  Rules
IPSec that  is  supported by the  machine conforms  to  RFC2401, RFC2402, RFC2406, and  RFC4305.

							Before using IPSec for  encrypted  communication,  you need to  register  security policies (SP).  A security policy consists of the  groups of
settings described below. Up to  10 policies can be registered. After registering  policies, specify  the  order in which they are  applied.
Selector
Selector  defines conditions  for  IP  packets  to  apply  IPSec communication.  Selectable  conditions  include  IP  addresses and  port
numbers  of the  machine and  the  devices to  communicate with.
IKE
IKE configures the  IKEv1 that  is  used for  key  exchange  protocol. Note that  instructions vary depending on  the  authentication me thod
selected.
[Pre- Shared Key  Method]
A key  of up  to  24 alphanumeric  characters  can be shared  with the  other devices.  Enable SSL  for  the  Remote  UI before specifying   this
authentication method (
Enabling  SSL Encrypted Communication for the Remote  UI ).
[Digital Signature Method]
The machine and  the  other devices authenticate each other by mutually verifying their  digital signatures. Generate  or install the  key
pair  beforehand (
Configuring  Settings  for Key  Pairs and  Digital Certificates ).
AH/ESP
Specify the  settings for  AH/ESP,  which is  added to  packets  during IPSec communication.  AH and  ESP can be used at the  same time.
You  can also  select whether  or not  to  enable  PFS  for  tighter security.
Start  the Remote UI  and  log  on in System Manager Mode.  Starting Remote UI
Click [Settings/Registration].
Click [Security  Settings]  [IPSec Settings].

							[Select Algorithm]
Select the  [ESP], [ESP (AES-GCM)], or [AH (SHA1)] check  box(es)  depending on  the  IPSec header  and  the  algorithm used. AES-
GCM  is  an  algorithm for  both  authentication and  encryption. If  [ESP] is  selected,  also  select algorithms  for  authentication and
encryption from the  [ESP Authentication] and  [ESP Encryption]  drop-down lists.[ESP
Authentication] To enable  the  ESP authentication,  select [SHA1] for  the  hash  algorithm.  Select [Do Not Use] if  you want
to  disable the  ESP authentication.
