Image 4-4-2: Firewall > General
4.4.2 Firewall > General
The General Firewall settings allow users to enable or disable the firewall, and to decide which areas of the
modem to protect. The Firewall can also be reset to factory defaults from this area of the WebUI.
In a cellular device such as this, it is highly recommended to configure the firewall to protect any devices
connected to the modem, and to control data usage. This is especially important with units set up with a
public IP address as the modem is effectively on the public internet and is susceptible to a wide range of
threats which may severely impact the data usage. This can be avoided by blocking all Cellular traffic and
setting up specific rules to either open only used ports, or even restrict access to specific IP/networks.
WAN Remote Management
Allow remote management of the IPnXGii on the WAN side using the
WebUI on port 80(HTTP), and 443 (HTTPS). If disabled, the configuration
can only be accessed from the LAN (or Cellular if enabled)..
Values
Enable
/ Disable
Carrier Remote Management
Allow remote management of the IPnXGii from the Cellular side of using
the WebUI on port 80(HTTP), and 443 (HTTPS). If disabled, the
configuration can only be accessed from the LAN (or WAN if enabled)..
Values
Enable
/ Disable
For best practices and to
control data usage it is
critical that the firewall be
configured properly.
It is recommended to block
all incoming Cellular traffic
and create rules to open
specific ports and/or use
ACL lists to limit incoming
connections.
WAN Request
When Blocked the IPnXGii will block all requests from devices on the WAN
unless specified otherwise in the Access Rules, MAC List, IP List
configurations. Access to ports 80 (HTTP) and 443 (HTTPS-if enabled), is
still available unless disabled in the
WAN
Remote Management
option.
Values
Block
/ Allow
Carrier Request
When Blocked all requests from devices on the Cellular (Wireless Carrier)
side will be blocked, unless specified otherwise in the Access Rules, MAC
List, IP List configurations. Access to ports 80 (HTTP) and 443 (HTTPS-if
enabled), is still available unless disabled in the
4G
Remote Management
option.
Values
Block
/ Allow
When Carrier Request is
set to ‘Allow’ the modem is
open to anyone, this is not
recommended as it may
impact data usage from
unwanted sources.
