Upgrading Notes
---------------

To upgrade, use the "Firmware Upgrade Utility" which is part of
the Vigor2900 router tools. After upgrading successfully, the new firmware
version will be shown on the front page of the web configurator.

The .RST file contains complete factory default settings and will wipe
out all existing router settings.  The .ALL file contains firmware only
and should retain your existing router settings.

Do not attempt to restore old settings from a configuration backup file which
was taken from a difference firmware version.

 - Support IP range in IP filter rules

 - Display more detail information in NAT session table
 - Support NAT loopback for 2nd subnet 

[Corrected Problems]
 - Buffer leakage caused by L2TP StopCCN messages
 - IP filter failed to handle port 65535
 - Call schedule not working for VPN profiles 17-32 
 - Can not set More route for Lan-to-Lan VPN profiles 17-32
 - Unable to set VLAN and Port Rate Control by FireFox
 - FTP traffic unable to pass NAT


[Notes]
 - How to find the Wireless Hardware Version:
   In the "Wireless LAN Setup" > "Wireless Information" > "Firmware Version", the last
   digit is the Wireless Hardware Version.  For example, v1.2.8.16.04.2 means the
   wireless hardware version is 2.

 - Time schedule of IP filter, MAC Address Control, P2P/IM blocking and URL filter: 
   Each of these firewall functions has 4 time schedule profiles. Each profile 
   represents one of the 15 profiles in Advanced Setup/Call Schedule Setup. Note that
   only time settings in the profile are used by firewall functions. Other settings 
   like Action and Idle Timeout will be ignored by firewall functions.
   
 - MAC Address Control: Can be used to assign the time that a MAC is allowed to pass 
   the router. It can also be used to filter MACs that are not explicit specified in 
   the list. Note that this function only checks source MAC of packets from LAN side.
 
 - DOS Defense: The way to defense flooding attacks before this release depends on the
   total number of attacks detected on the WAN interface. In this release, each port
   will detect the number of attacks and defense themselves when threshold is reached.
   DOS defense function also works on LAN interface.
   A maximum number limitation of syslog is given in this release(about 10 per second) 
   to prevent the syslog server from DOS attacks by syslog messages.

 - Block IM: 3 Instant Messenger applications(MSN Messenger, Yahoo Messenger, ICQ/AOL)
   can be blocked. 4 time schedule profiles can be used to specify the time to block IM.
   
 - URL Content filter allow/block option: When Block option is selected, URLs matching 
   the Keywords will be blocked. When Allow option is selected, URLs matching the 
   keywords are allowed to pass, others will be blocked.
   
 - IKE/IPSEC DPD(Dead Peer Detection) function: is used to disconnect the IPSec tunnel
   when the peer is detected as dead. Note that both peer must support DPD for this
   function to work.
 
 - DNS server for router: A new telnet command "ip dns" has been added to set the DNS 
   servers used by router. The router tries to select a primary and a secondary DNS 
   server in the following order: 
   1. The DNS server set by "ip dns" command(in Static or Dynamic IP page)
   2. The DNS server given by the Internet Access server(PPPoE or PPTP/L2TP server)
   3. The DNS server for DHCP clients(in LAN TCP/IP and DHCP Setup page)
   4. Default DNS server(194.109.6.66 and 194.98.0.1)
   The telnet command "srv dhcp dnsmanl" is not supported in this release. The "ip dns"
   command also displays the active DNS server.
 

Changes Since Firmware 2.5.4.3
------------------------------


[New Features]:

 - DHCP over IPSec
 - Apply Firewall/IPFilter to incoming traffic of VPN connections
 - P2P blocking

[Improvement]

 - Better VPN rekey method for compatible with Nortel router
 - Support TCP defragment with size limitation of 2000 bytes


[Corrected Problem]

 1. Disconnect ISDN backup when WAN is reactive in DHCP client mode

   when the profile is using PAP ONLY

  3. Failed to clean TCP sessions having status 0 in NAT session table (Mantis 0952)
  4. Failed to clean TCP sessions having status 3 in NAT session table (Mantis 1065)
  5. IPSec tunnel display error in routing table (Mantis 1007)
  6. Routing table error when 'change default route' is enable in L2L VPN tunnel (Mantis 0664)


[Notes]

 - The VPN filter only works with direction IN
 - Enabling P2P blocking does not disconnect current P2P data connections
