An example with an altered configuration is shown next.

192.168.1.1 > bridge

192.168.1.1 bridge> portfilter 2 1 3

192.168.1.1 bridge> portfilter 3 1 2

This example sets the allowed outgoing bridge ports of port 2 (DSL port 1) to port 1 (Ethernet port) and port 3 (DSL port 2). The allowed outgoing bridge ports of port 3 (DSL port 2) are set to port 1 (Ethernet port) and port 2 (DSL port1). This way, DSL ports 2 and 3 can communicate with each other and the Ethernet port. You can see the effects of this example by using the following command:

192.168.1.1 bridge> portfilter

Port 1 (ethernet):

1

all

Port 2 (dsl1):

3

Port 3 (dsl2):

Figure 28-3 Portfilter Command Example 2

The following figures illustrate the above example. Notice that ports 2 (DSL port 1) and 3 (DSL port 2) are able to communicate with each other, as well as with the Ethernet. All of the other ports will only be able to communicate with the Ethernet port.

The following figure illustrates the

192.168.1.1 bridge> portfilter 2 1 3

command line. Port 2 (DSL port 1) is able to send to both the Ethernet port and port 3 (DSL port 2).

Figure 28-4 Example of Modified Port Filter Port 2

The following figure illustrates the

192.168.1.1 bridge> portfilter 3 1 2

command line.

Port 3 (DSL port 2) is able to send to both the Ethernet port and port 2 (DSL port 1).
