Limit network access

By default your server, once it is booted and its network activated, is available from anywhere on the Internet on all available TCP and UDP ports. This is the most common scenario, since you typically want e.g. a web server to be available to user from anywhere. Limiting access to other ports is typically done by a fire-wall running on the server. You may however choose to limit network access to your server using the built-in functionality of Stabile networking.

To limit access you should fill out the ports field with a comma-separated list of ports you want to give access to (TCP and UDP). Access to all other ports is then disallowed. Each port may be prefixed with an IPv4 address or network, if you want to limit access to this port to a specific host or network. You may repeat ports prefixed with different hosts or networks.

Some examples:
80,443,195.41.32.0/24:10000,195.41.32.10:22
25,110,143,195.41.32.10:22
