How to set TCP/IP filtering for the TCP and UDP ports on a particular NIC Card on a Windows 2000/2003/2008 server? Apparently this can be done using registry setting, however I would like to have some script or commands to do the same without directly calling registry.
Are you looking only for command line solution?
To enable filtering using GUI check this http://support.microsoft.com/kb/309798
If you want to do it from command prompt only why can't use 'reg' command to edit the registry.. AFAIK there's no other in-built command to configure filtering..I think you already know the 'reg' command but looks like you dont want to use this method or may be this does not work in your problem context..
Otherwise see below example to enable filtering
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v EnableSecurityFilters /t REG_DWORD /d 1 /f
Let me know if this helps..
Hi,
Thanks for the response. Even I searched for commands to do the filtering, but.., I guess I would have to create reg entries for doing so.
Ideally we have two nics, on one of them we use TCP/IP port filtering to restrict a set of applications to connect to that server over that particular NIC. Since the ports are large in no., I was looking for something which could take out the pain from doing the thing manually.
