Editing advanced firewall settings
Advanced firewall configuration allows advanced users to further configure the system software firewall.
You should use this feature only if you have advanced knowledge about firewalls and networking.
If an Inbound box is checked, the firewall allows the corresponding protocol to pass through from the
Internet to the network. If an Outbound box is checked, the firewall allows the traffic from the network to
pass through the firewall to the Internet. You must click
SAVE for the changes to take effect.
Note: Allowing inbound traffic does not mean that the firewall automatically allows this type of traffic to
pass through the firewall to the network. Even if a particular protocol/application type is allowed via the
Advanced Configuration settings, the firewall still checks and blocks all unsolicited traffic from the
Internet unless the firewall is configured to allow the traffic through using an application profile.
Note: Firewall filtering takes precedence over application hosting. If you disable the incoming traffic,
you may disable support for hosted applications that require that type of inbound communication.
