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

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.

       12.6 Improved SAR rx queue that may be cause packets holding on queue.

    [Fixed Issues]:
	1. PPTP connection problem with Mac OS X.
	2. to Vigor2300, LPD driver improvement.
	3. port 1732 could be found even PPTP connection is disabled.
	4. port 113 could be found via WAN side.
	5. PPP/RADIUS problem if remote PPP ( dial-in ) request call-back option.

 	7. The SNMP contact information is incorrect
	8. DHCP can not change gateway in the 2nd subnet
	9. Allow entering (but pointless) blank string in DDNS setup. 
       10. FTP with port redirection didn't work, but ok with DMZ sometimes.	
       11. In Vigor2200USB, FTP can not work with port redirection since the port-map 
           entry table could be reproduced to fill out.	
       12. Problem if sending a long URL to Vigor's WUI.
       13. Telnet's ip ping command in Vigor router can not access the state routing 
           subnet.
       14. the problem that setting static/Dynamic IP or PPP, the router changed the 
           ISDN Link type to BOD.		
       15. "Peer ISDN Number or Peer VPN server IP" in WUI's "LAN-to-LAN Dial         
           Profile Setup>Dial-In Settings" can not be stored the last digit if the length 
           of stored string = 15.
       16. packet trigger can not work while setting the more-route subnet. 
       17. If subnet is larger or smaller than CLASS-C, DHCP server can not work properly.   
       20. DHCP server fixed IP setting problems via telnet command.
       22. Static routing improved where destination IP in routing table is not the 
           subnet's boundary ( ex. 195.145.12.193, static route can not work, but 
           192.145.12.192 is ok ).
       23. NAT issue where some UTP port may not be translated.

       30. sometimes, WUI and telnet can not be accessed any more.	
       32. Improved IKE pass through function
