Fig u re 32.10. Firewall Co n f ig u rat io n
If Disable firewall is selected, the system allows complete access to any active services and
ports. No connections to the system are refused or denied.
Selecting Enable firewall configures the system to reject incoming connections that are not in
response to outbound requests, such as D NS replies or DHCP requests. If access to services
running on this machine is required, you can choose to allow specific services through the firewall.
Only devices configured in the Network Configuration section are listed as available Trusted
devices. Connections from any devices selected in the list are accepted by the system. For example,
if eth1 only receives connections from internal system, you might want to allow connections from it.
If a service is selected in the Trusted services list, connections for the service are accepted and
processed by the system.
In the Other ports text field, list any additional ports that should be opened for remote access. Use
the following format: port:protocol. For example, to allow IMAP access through the firewall,
specify imap:tcp. Numeric ports can also be specified explicitly; to allow UD P packets on port 1234
through the firewall, enter 1234:udp. To specify multiple ports, separate them with commas.
