Network goes down when installing ipfw

[Kulamani Sethi]

Dear all,

     I am using ipfw3. When i am installing ipfw driver in windows-7
machine the network goes down. If uninstall that driver again then network
comes automatically. That means ipfw driver does not support.

            I have also digitally signed by Microsoft kernel mode signing
process for authenticate the publisher.


Process of installing: Local Area Connection-> properties -> Install ->
service -> Add ->OK (I can also see there message by system  "Driver
digitally signed")

Could anyone please help me for this issue. Thanks in advance.
