Edit Advanced Firewall Settings
NOTE: These features should be used only if you are thoroughly familiar with
firewalls and networking.
The 'Edit advanced firewall settings' page allows you to
configure advanced features on your firewall.
Security Settings
The BT Business Hub firewall provides a high level of security.
You can configure the firewall to provide advanced security
features, including stealth mode, block pings, or strict UDP
session control.
• Stealth Mode. When in stealth mode, the BT Business Hub
firewall will not return any information in response to
network queries; that is, it will appear to anyone who tries
to access your network that your network does not exist
• Block Ping. Enabling this feature ensures that your network
will block all ping requests
• Strict UDP Session Control. Enabling this feature provides
increased security by preventing the BT Business Hub from
accepting packets sent from an unknown source over an
existing connection
Inbound and Outbound Control
The Inbound and Outbound Control page displays some common protocol
types. When one of the Inbound protocol boxes is checked, the firewall
allows the corresponding protocol to pass through from the Internet to
the network. If one of the Outbound protocol boxes 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 par
ticular 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 tr
affic, you may disable suppor
t for hosted applications
that require that type of inbound communication.
