Filter Hook driver problem

NTDEV
1

Hello!

I’m wriring a filter hook driver. The documentation says that, in order to install a new filter hook driver, it is necessary to send an IOCTL to \Device\Ipfilterdriver.
However the IoGetDeviceObjectPointer returns an error and by inspecting the system using WinObj I’m not able to find a device called IpfilterDriver.

Anyone has any help ?

Thanks
Matteo

It is not started by default - you have to enable it.
At the command line type:
net start ipfilterdriver.

You may want to change its startup type to automatic. I believe all you
need to do is to open TCP/IP properties on any of the network connections
and in the Advanced tab enable IP filtering.

I have a working sample somewhere - can share it if you want
