#### Allowing and Blocking Inbound Connections

By default, all inbound connections that are not explicitly allowed are blocked.

To allow inbound connections to a service:

1. Go to Server > IP Addresses > Firewall.
2. Click the network interface you need.

   Note. Configuring firewall for specific network interfaces is only available under Microsoft Windows Server 2003. If you are using Microsoft Windows Server 2008, go to the Firewall Rules tab.

3. Click Add Firewall Rule, and specify the following properties:
   - The rule name for future reference
   - The port or port range and the protocol for which inbound connections must be allowed
4. Leave the Switch on rule check box selected, if you wish to apply the rule immediately.
5. Click OK.

To block the previously allowed inbound connections to a service:

1. Go to Server > IP Addresses > Firewall.
2. Click the network interface you need.

   Note. Configuring firewall for specific network interfaces is only available under Microsoft Windows Server 2003. If you are using Microsoft Windows Server 2008, go to the Firewall Rules tab.

3. Select the check box corresponding to the rule that allows connections to the respective service, and click Remove Selected.

   Removing a rule blocks the connections that were specified in that rule.
