WHAT'S NEW IN VERSION 4.0

New features incorporated in v4.0 are:

* AppleTalk support
* Full SNMP manageability
* Quick Setup program
* IP/IPX/AppleTalk spoofing
* PPP compression



DIFFERENCES BETWEEN VERSIONS 3.x & 4.0

* Use the default 4.x USR initialization script. This script takes 
  the modems out of auto-answer mode for more flexible control.
  The 3.x initialization script is not valid in 4.x.

* Location users have been merged into the User Table. Location users 
  are known as dialout users in v4.0. All information associated with 
  the location user has been moved into the user record. This allows a
  dialout user (location) to be defined in the RADIUS database. As a 
  result, the RADIUS attribute "dialback-name" is no longer supported.
  The dialback or dialout functionality is now completely defined in
  the user records. This design supports roaming dialback users. 
  Location names are converted to "location_name-l".

* The following RADIUS attribute is NOT supported:

  CALLBACK-ID  - Location name that 3.x systems use

* Modems are busied out by disabling the modem interface. A modem is
  returned to service by enabling the modem interface.

* Interface names have been expanded to 3 characters to describe the
  interface type. Modem interfaces are: mod:1 through mod:16. The 
  Ethernet interface is eth:1.

* User passwords are required in 4.x, unlike 3.x. The migration
  process automatically creates passwords by appending _P to the end
  of the user name. Passwords for 3.x "location" users are created 
  simply as the location name. 

* Filter rules have been completely revamped in v4.0. Filter rules 
  must be created in an off-line editor and TFTPed into the NETServer.
  A future release will allow you to create filter files from the CLI.

* IP address spoofing, NIS and dialback delay features are not 
  supported at this time.

* ICMP logging, proxy ARP and login authentication features are not
  migrated at this time.



CLARIFICATIONS AND MODIFICATIONS

Be aware of the following clarifications and modifications.

* PPP compression is supported on the 8-port NETServer Plus but not 
  supported on the 16-port NETServer Plus at this time.

* Software downloads of upgraded NETServer images MUST be accompanied 
  by downloads of I-modem code as well, for the unit to work correctly. 
  Also, you must have, at a minimum, the following code sets already 
  installed before using NETSwitcher:

	NETServer code: 	v3.2.5
	I-modem code:           v2.1.5
	V.34 modem code:	v1.0.8

* No filter data is migrated between platforms.

* Netmasks Table data is not migrated between platforms.

* Upgrades using the PCSDL program (not NETSwitcher) of code from 3.x 
  to 4.0 require the unit be re-set to factory defaults using DIP switch
  #4 in the ON position. Once the upgrade is complete, return this
  switch to the OFF position. Be sure this switch is normally left in
  the OFF position or you will lose your configuration every time you
  boot.  It should only be ON for the 3.x to 4.0 upgrade and to 
  recover from a lost password or file corruption.

* NETServer Manager is not compatible with NETServer Plus - you need 
  NETServer Manager Plus.  Also, NETServer Manager will not upgrade your
  NETServer to NETServer Plus.  If you have already attempted to upgrade
  using NETserver Manager and your unit no longer functions, you will 
  need to do the serial line upgrade process using PCSDL.

* DIP Switch #6 should remain in the OFF position. If enabled, typing
  Ctrl C from the Console port puts the NETServer in DEBUG mode.

* The RADIUS Framed-MTU attribute is being ignored when establishing PPP
  connections. The MTU from "default" user is the value NETServer uses.

* Dial-in clients must be set up to use a host netmask 
  (255.255.255.255).

* Quick Setup was designed to run only once. It runs automatically 
  whenever there is no configuration saved.  You can return the box to 
  its uninitialized state with the "delete configuration" command so 
  that Quick Setup will run again.

* The "New" option in NETServer Manager Plus will query for new devices
  with an IP broadcast.  You must be on the same network segment for 
  this to work. If you can not run this from the same network segment,
  the console Quick Setup has an option to configure just the 
  essentials to allow NETServer Manager Plus to reach NETServer Plus.

* PPP Negotiation for DNS servers is not implemented in this code.  
  Windows 95 clients must configure this manually.

* RADIUS source port is always 1645 for both security and accounting.

* To attach to a modem from the console, refer to the manual and do the
  following:  Create a modem group if one is not suitable.  Set up a 
  TELNET service for dial out.  TELNET to the new service.

* The NETServer Plus 16-port units will accept four ARAP calls only due
  to memory limitations. NETServer Plus 8-port units will take 8 ARAP 
  calls.

* MR# 307  The "traceroute" command is currently not implemented.

* MR# 566  Beginning with version 4.0, there is no longer support for 
  PPP or SLIP on the console port.

* MR# 1123  Disabling an interface will also busy it out.  However, if
  you save this configuration and reboot the NETServer Plus, the 
  interface will be disabled but not busied out.

* MR# 1125  In many cases, changing framed routes will require you to 
  disable and enable the user.  This is not always consistent as other
  times you don't need to do this.

* MR# 1128  Changing the IP address is done with the "reconfigure"
  command, not the "set" command.

* MR# 1172  CSLIP connections may not always ping without packet loss.

* MR# 1178  Multiple CHAP challenges are not supported.  Only 
  challenge the NETServer Plus right after initial LCP negotiations.

* MR# 1208  Deleted users are removed immediately without needing a 
  "save all" command. However, added users will be lost unless a 
  save all is issued.

* MR# 1424  The timeout value in the "echo" command is actually 1/10th
  seconds, not full seconds as indicated by the software.
