Configuring TCP/IP filtering

[Rick Charnes]

When the Blaster worm hit, Microsoft's web site was pointing folks to
http://support.microsoft.com/?id=309798 for help in configuring TCP/IP
filtering. The steps given in that article are:

1. Click Start, point to Settings, click Control Panel, and then double-
click Network and Dial-up Connections.
2. Right-click the interface on which you want to configure inbound
access control, and then click Properties.
3. In the Components checked are used by this connection box, click
Internet Protocol (TCP/IP), and then click Properties.
4. In the Internet Protocol (TCP/IP) Properties dialog box, click
Advanced.
5. Click the Options tab.
6. Click TCP/IP filtering, and then click Properties.

I'm running Windows 2000 Professional. When I click the Options tab on
Step 5, I don't see an item TCP/IP filtering. The only item I see is IP
Security. Any thoughts about what could be going on? Thanks.

That's easy to click but must harder to do what you wish.

If you are up for learning something new, download the newer
version of IPSecPol from MS and learn to apply PASS and
BLOCK "IPSec filters"

Most people incorrectly think IPSec is ONLY about encrypting
packets but it is also a better "filter" than the other built-in filtering.

It's tricky to start, but if you try and need help someone here will
likely help.

Sorry, not sure I understand you. When other folks follow these steps
and click on that Options tab, is "TCP/IP filtering" there? I only see
"IP Security". Thanks.

There are two choice in the NIC\IP\Advanced\Options tab:
IPSecurity and Filtering.

IPSec is more capable and harder to learn initially.

Setting it is actually easier from the command line ONCE
you get over the learning curve.

I am having the same problem as Rick Charnes. What gives?
