 Chapter 16 The Firewall Screens

User’s Guide

16.4.2  Guidelines For Enhancing Security With Your Firewall

1

Change the default password via web configurator.

2

Think about access control before you connect to the network in any way.

3

Limit who can access your router.

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.

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.

6

Protect against IP spoofing by making sure the firewall is active.

7

Keep the firewall in a secured (locked) room.

16.4.3  The “Triangle Route” Problem

A traffic route is a path for sending or receiving data packets between two 
Ethernet devices. You may have more than one connection to the Internet 
(through one or more ISPs). If an alternate gateway is on the LAN (and its IP 
address is in the same subnet as the WiMAX Device’s LAN IP address), the 
“triangle route” (also called asymmetrical route) problem may occur. The steps 
below describe the “triangle route” problem. 

1

A computer on the LAN initiates a connection by sending out a SYN packet to a 
receiving server on the WAN.

2

The WiMAX Device reroutes the SYN packet through Gateway A on the LAN to the 
WAN. 

3

The reply from the WAN goes directly to the computer on the LAN without going 
through the WiMAX Device.
