IPsec and NETSH

[Amit]

I have win2k server, with ICS enabled serving 20 clients.
Is there a way i can block all trafiic from say machine
xxx.xxx.xxx.xxx on my LAN bu just running a batch file?
I think i might have to use IPSEC policy to do this?
Netsh can disable the entire LAN card but that will block
internet access to all 20 clients.
Any suggestions?

Hi Amit,

How to Block Specific Network Protocols and Ports by Using IPSec:

BTW how do you disable NIC with netsh? If you mean "netsh interface set
interface name = IfName admin = DISABLED" command then AFAIK it works only
for non-LAN interfaces.
What i use to disable NIC is devcon.exe though it is a little tricky.


hth,
