Port numbers used by Lion Server servicesĪ firewall blocks incoming traffic through software ports (settings identified by port numbers) and by port type: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). Regardless of whether you're running a firewall on Lion Server or somewhere else, the next few sections provide useful information. In this case, the server needs to be connected to the router via Ethernet. You also need to run a firewall on the server if your Internet connection goes directly into a wireless router, and the router doesn't have a firewall built in or running on it. You do need to run a firewall on your Mac server if it's acting as an Internet gateway, with the Mac in between the Internet connection and the local network. If your network already has a firewall on another server or a router or other security gateway appliance, you may not need to run Lion Server's firewall. For example, if your users try to access a website, you want traffic from web servers to reach the users.

If you're running a firewall, your job is to configure it to allow incoming traffic in response to outgoing traffic from your users. A firewall blocks certain types of incoming traffic from the Internet while allowing outgoing traffic to the Internet.
