Services and Ports
Ap
pendix
If your server connects to the Internet through a cable router, DSL router, or other
network router, you can configure port forwarding (port mapping) to allow access to
some services from the Internet while protecting other services and other computers
on your network.
Use the following table to determine the port numbers for the services that you want
to expose on the Internet. Configure your router to forward only those ports to your
server’s IP address.
Some Internet routers may ask you to specify TCP or UDP for each port, while other
routers don’t. For specific information about how to configure port forwarding on your
router, see its documentation.
If your local network has a separate firewall device and you want to allow access to
some services outside your local network, ask the firewall administrator to open the
firewall for the communications ports and protocols that your services use. Use the
following table to determine the port numbers you need to have opened on the
firewall.
