We are using SBS 2003 Premium Edition. One of the Client machine is running Apache Web Server. Outside users are accessing the Web Server.

I want to create IP Filters, so that IP addresses I have specified here only should access our network.

Where should I create the IP filters and how to set it. Is there any option in SBS 2003 Premium edition. I have not installed ISA server.

I didn't enable "Basic Firewall", instead I have checked the option "Don't change the configuration"..

Here's a way how to do it....
1. Click Start, point to Control Panel, right-click Network Connections, and then click Open.
2. Right-click the network connection where you want to configure inbound access control, and then click Properties.
3. Under adaptorName Connection Properties on the General tab, 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. Click to select the Enable TCP/IP Filtering (All adaptors) check box.

When you select this check box, you enable filtering for all adaptors. However, filter configuration must be completed on each adaptor. When TCP/IP Filtering is enabled, you can configure each adaptor by selecting the Permit All option, or you could allow for only specific IP protocols, TCP ports, and UDP ports to accept inbound connections. For example, if you enable TCP/IP Filtering and you configure the external network adaptor to permit only port 80, this lets the external network adaptor to accept Web traffic only. If the internal network adaptor also has TCP/IP Filtering enabled but is configured with the Permit All option selected, this enables unrestricted communication on the internal network adaptor.
8. Under TCP/IP Filtering, there are three columns with the following labels: • TCP Ports
• UDP Ports
• IP Protocols
In each column, you must select one of the following options: • Permit All. Select this option if you want to permit all packets for TCP or UDP traffic.
• Permit Only. Select this option if you want to permit only selected TCP or UDP traffic, click Add, and then type the appropriate port or protocol number in the Add Filter dialog box. You cannot block UDP or TCP traffic by selecting Permit Only in the IP Protocols column and by then adding IP protocols 6 and 17.
You cannot block ICMP messages, even if you select Permit Only in the IP Protocols column and then you do not include IP protocol 1.

Thanks Arani, If I do the changes here, only particular IP address coming from outside can access. Thus it restricts other IP addresses.

Is there any options in RRAS on SBS 2003.
