How to configure TCP/IP security

loadTOCNode(2, ‘summary’); To configure TCP/IP security:

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 .
7. Select the Enable TCP/IP Filtering (All adapters) check box. When you select this check box, you enable filtering for all adapters, but you configure the filters on a per-adapter basis. The same filters do not apply to all adapters.
8. There are three columns with the following labels:

TCP Ports
UDP Ports
IP Protocols

In each column, you must select either of the following options:

Permit All . If you want to permit all packets for TCP or UDP traffic, leave Permit All activated.

Permit Only . If you want to allow only selected TCP or UDP traffic, click Permit Only , click Add , and then type the appropriate port in the Add Filter dialog box.

If you want to block all UDP or TCP traffic, click Permit Only , but do not add any port numbers in the UDP Ports or TCP Port column. You cannot block UDP or TCP traffic by selecting Permit Only for IP Protocols and excluding IP protocols 6 and 17.

Note that you cannot block ICMP messages, even if you select Permit Only in the IP Protocols column and you do not include IP protocol 1.

TCP/IP Filtering can filter only inbound traffic. This feature does not affect outbound traffic or response ports that are created to accept responses from outbound requests. Use IPSec Policies or packet filtering if you require more control over outbound access.
