Configuring the Firewall
The Dominion PX has a firewall that you can configure to prevent specific
IP addresses and ranges of IP addresses from accessing the Dominion
PX device. When the Dominion PX was initially configured, you were
prompted to enable or disable IP access control. If you selected Disable
(the default), the firewall was not enabled.
To configure the firewall:
1. Enable the firewall. See Enabling the Firewall (on page 98).
2. Set the default policy. See Changing the Default Policy (on page
99).
3. Create firewall rules specifying which addresses to accept and which
ones to discard. See Creating Firewall Rules (on page 99).
Changes made to firewall rules take effect immediately. Any unauthorized
IP activities cease instantly.
Note: The purpose of disabling the firewall by default is to prevent users
from accidentally locking themselves out of the device. See
Initial
Network and Time Configuration (on page 19).
Enabling the Firewall
The firewall rules, if any, take effect only after the firewall is enabled.
To enable the Dominion PX firewall:
1. Choose Device Settings > Security. The Security Settings page
opens. Locate the panel labeled IP Access Control.
2. Select the Enable IP Access Control checkbox. This enables the
firewall.
