Hi all,
 
Here is a new beta driver for LNSFW.SYS/Internet Filtering.
 
The main change is about the TCP SPI:
- bug fixes (related to bad detection of closing state)
- 256 entries
- improvements regarding timeout handling
 
Some other changes in this new driver:
- fix for "Different And" criteria which was not working (thanks Phant0m  )
- support for IP Fragmented packets. When an IP datagram is fragmented, now the ruleset is applied only to the first packet of the datagram to know the behaviour (block/allow/alert), and same behaviour is applied to the other packets of the datagram.
To activate this feature you need to add the following registry key (and reboot):
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lnsfw1]
"IPFragActive"=dword:00000001
 
This new driver is available to download here:
http://looknstop.soft4ever.com/Beta/lnsfw/lnsfw.sys
 
To install it:
- rename your current C:\WINNT\system32\drivers\lnsfw.sys into lnsfw.old (to come back to a working driver in case of problem)
- put the new file in C:\WINNT\system32\drivers
- reboot
 
Note this is anyway a beta driver, so you should not use it if you are afraid of encountering problems...
