Step 3

Limit who can access your LTE Device.

Step 4

Don't enable any local service (such as Telnet or FTP) that you don't use. Any enabled service

could present a potential security risk. A determined hacker might be able to find creative ways

to misuse the enabled services to access the firewall or the network.

Step 5

For local services that are enabled, protect against misuse. Protect by configuring the services to

communicate only with specific peers, and protect by configuring rules to block packets for the

services at specific interfaces.

Step 6

Keep the firewall in a secured (locked) room.

10.6.2 Security Considerations

Incorrectly configuring the firewall may block valid access or introduce security risks to the LTE Device

and your protected network. Use caution when creating or deleting firewall rules and test your rules after

you configure them.

Consider these security ramifications before creating a rule:

Step 1

Does this rule stop LAN users from accessing critical resources on the Internet? For example, if

IRC is blocked, are there users that require this service?

Step 2

Is it possible to modify the rule to be more specific? For example, if IRC is blocked for all users,

will a rule that blocks just certain users be more effective?

Step 3

Does a rule that allows Internet users access to resources on the LAN create security

vulnerability? For example, if FTP ports (TCP 20, 21) are allowed from the Internet to the LAN,

Internet users may be able to connect to computers with running FTP servers.

Step 4

Does this rule conflict with any existing rules?

----End

Once these questions have been answered, adding rules is simply a matter of entering the

information into the correct fields in the web configurator screens.

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address

is assigned at the factory and consists of six pairs of hexadecimal characters, for example,

00:A0:C5:00:00:02. You need to know the MAC address of the devices to configure this screen.

11.2 The MAC Filter Screen
