are replaced on a connection-by-connection basis, which makes it impossible to 
know the exact address and port on the wire. Therefore, the BCM50a Integrated 
Router applies the protocol filters to the native IP address and port number before 
NAT for outgoing packets and after NAT for incoming packets. On the other 
hand, the generic, or device filters are applied to the raw packets that appear on 
the wire. They are applied at the point when the BCM50a Integrated Router is 
receiving and sending the packets; for example. the interface. The interface can be 
an Ethernet port or any other hardware port, as illustrated in 

Figure 63

Protocol and Device Filter Sets

Firewall Versus Filters

Firewall configuration is discussed in 

Chapter 10, “Introducing the firewall,” on 

page 115

 

chapters

 

of this manual. Further comparisons are also made between 

filtering, NAT and the firewall. 

Applying a Filter 

This section shows you where to apply the filters after you design them. The 
BCM50a Integrated Router already has filters to prevent NetBIOS traffic from 
triggering calls, and block incoming Telnet, FTP and HTTP connections.

Note: 

Nortel recommends that you apply filters if you do not activate 

the firewall.
