***************************************************************************************

Note : The RST file will clear out all existing router settings back to factory
defaults. You must use the RST file if you are upgrading from firmware 2.1r or
earlier, or experience unusual results after upgrading with the ALL file.

The special 'UK2' version of the firmware is only for use where the
standard firmware cannot sync. reliably on your ADSL line, for example
on very long line with high attenuation. Use the standard firmware otherwise.

Do not then attempt to restore old settings from a backup file made with
from previous firmware or from another model. After upgrading, check that
your web configurator shows the firmware version/build listed above. 

    [Changes / New functions since firmware 2.5.5_UK]

      [1. New functions]
	1. Add Cone NAT facility; this should provide greater compatibility
           for various multimedia apps through NAT.
	2. Support defense Worm function and disable by default.
        4. Support telnet command "show session" to see the session usage.


      [2. Fixed Issues ]
        1. If the user doesn't assign DNS server in the router the DHCP 
           server wasn't always assigning the router IP as the DNS server
           in order to use the DNS proxy facility by default.
	2. Fixed a DNS proxy error whereby it returned the wrong source IP.
        3. Fixed a MRU/MRRU negotiation issue.
        4. Fail to change the WAN IP address from the Internet by using telent.
	5. WAN using DHCP client. The IP address could sometimes become
           0.0.0.0 after doing some telnet configuration.
	6. When ISDN Bandwidth-on-demand (BOD) is used with Dual-ISP, transmission
           of packets may sometimes packet may cease.
           successfully send out.
	7. Add ISDN Call_Bumping function, for out-going call from other ISDN
           phone on the same bus (does not include BT Highway POTS ports).
	8. After PPPoE backup to ISDN, ISDN would not always drop when PPPoE resumes.
	9. ISDN Layer 1 driver enhancement, to handle un-stable ISDN S-bus signal.
 
       [ 3. Improved Issues ]
        1. Fixed eboot when handling malformed DNS/MX packet 
        3. DMZ host may crash the router under heavy load.
        4. Improved the uPNP's issue for My Network Places.
        5. Improved the L2TP performance.
        6. Change CLI command "wan mtu" into "wan ppp_mss"
        7. Vigor Router can pass the NetBIOS Broadcast packets through VPN Tunnel.
        8. The Remote Dail in VPN pass through from the Nat Host.
        9. If user doesn't assign DNS server in the router, the DHCP will assign 
           router IP as the DNS server.
	10. Corrected the DNS proxy error in wrong source IP.
        11. Fail to change the WAN IP address from the Internet by using telent.
	12. Fixed WAN IP from changing to 0.0.0.0 after telnet configuration.
	13. When ISDN Bandwidth-on-demand (BOD) work with Dual-ISP, packet may not
            successfully send out.
	14. Add ISDN Call_Bumping function, for out-going call from other ISDN phone
            on the same bus.
	15. After PPPoE backup to ISDN, ISDN will not drop when PPPoE resume.
	16. ISDN Layer 1 driver enhancement, to handle un-stable ISDN S-bus signal.
        17. VPN IPSec Interoperability with Cisco.
	18. Improve the VPN performance.(change VPN MTU to 1296).
	19. Improve DMZ with "Wan IP Alias". ( Multi-DMZ issue)
        20. Correct NAT loop-thru issue.
        21. Correct DSL default settings for UK.
	22. Correct ISDN 128k DNS issue.
        23. Correct NAT session Table status 3 issue. 
	24. Correct ARP Mechanism / Non Class C subnets issue.
        25. Correct buffer leakage while using PPTP passthrough.
        26. Correct buffer leakage while using L2TP passthrough.
        27. VPN cange default route will cause tunnel broken.
        28. Correct UDP Fragment can't send from lan to internet when WAN is PPPoE.
        29. Change PPPFSM timeout from 3 secs to 8 secs for some Radius server reply too slow.
        30. Add "adsl psd W x" to set any x value to psdm0.
        31. Correct 'asl ppp' command issue.


    [Changes / New functions since firmware 2.5.4_UK]
	1. Fixed "IP Filter/Firewall" config setting didn't clear bug after
           upgrade v2k6xxxx.rst. 

    [Changes / New functions since firmware 2.5.2_UK]

        1. Addressed ISDN detection issue (V26600X/W only)
        2. Fixed ARP request unicast problem. 

    [Changes / New functions since firmware 2.5_UK]

      [1. Improvements]
	 1. Improve ADSL auto-detecting.
            - The router will set up pvc1 for PPPoE/PPPoA when detected it.
            - The router will set up pvc2 for MPoA when detected it; MPoA
              is not available in the UK, so this facility is not used. 
         2. Improve telnet command "adsl ppp ..." to support multi-pvc setting.
            - The router will set up pvc1 for internet access when got "adsl ppp 0 ...".
            - else, the router will enable that pvc only.
         3. Correct ADSL interface values of MIB-II.  Add ADSL-LINE-MIB ( RFC-2662 ).

      [2. Fixed Issues ]
         1. Deny reply for unicast ARP request
         2. Static route failure when some specific IP filter setting.
         3. NAT failure on none directly connected subnet.
         4. Fail to configure a static route for a host route.
         5. Fail to configure the TCP/IP setting of LAN to LAN profile for the remote 
            network.
