Wireless Configuration

Unlike wired network data, your wireless data transmissions can extend beyond your walls and 
can be received by anyone with a compatible adapter. For this reason, use the security features of 
your wireless equipment. 

Restricting access by MAC address filtering adds an obstacle against unwanted access to your 
network, but the data broadcast over the wireless link is fully exposed. To block a determined 
eavesdropper, you should use one of the data encryption options of the firewall. Wired Equivalent 
Privacy (WEP) data encryption provides some security. However, a determined intruder can 
compromise WEP, there may be degradation of the data throughput on the wireless link, and WEP 
configurations can be less reliable. Unique to the FVM318, you can use the highly secure, reliable, 
high performance IPSec VPN communications protocols for your wireless connection.

Indoors, computers can connect over 802.11b wireless networks at a 

maximum range of up to 500 feet.

 Such distances can allow for others outside of your 

immediate area to access your network. It is important to take appropriate steps to 
secure your network from unauthorized access. The FVM318 firewall provides highly 
effective security features which are covered in detail in this chapter. Deploy the 
security features appropriate to your needs.
