Configuring the Firewall
The PXE has a firewall that you can configure to prevent specific IP
addresses and ranges of IP addresses from accessing the PXE device
or to prevent them from receiving any data from the PXE.
The PXE allows you to configure the firewall rules for inbound and
outbound traffic respectively. Inbound rules control the data sent to the
PXE, and outbound rules control the data sent from the PXE.
By default the firewall is disabled.
To configure the firewall:
1. Enable the firewall. See
Enabling the Firewall
(on page 87).
2. Set the default policy. See
Changing the Default Policy
(on page
3. Create firewall rules specifying which addresses to accept and which
ones to discard. See
Creating Firewall Rules
(on page 89).
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.
Enabling the Firewall
The firewall rules, if any, take effect only after the firewall is enabled.
To enable the PXE firewall:
1. Choose Device Settings > Security > IP Access Control. The
Configure IP Access Control Settings dialog appears.
2. To enable the IPv4 firewall, click the IPv4 tab, and select the Enable
IPv4 Access Control checkbox.
3. To enable the IPv6 firewall, click the IPv6 tab, and select the Enable
IPv6 Access Control checkbox.
4. Click
OK.
