SETTING UP PROTOCOL AND PORT FILTERING

Protocol ﬁltering allows you to control the types of protocols that the bridge is authorized to transmit and receive. The default setting allows the following protocols to be transmitted and received:

■IPX

■NetBEUI

■UDP/IP

■TCP/IP

To set up a list of authorized protocols:

1Under System Conﬁguration, click Protocol Filtering.

2In the Protocol Filtering page, click the Allow radio buttons next to the protocols that you want to authorize. Click the Block radio buttons next to the protocols that you want to disable.

3Click Save.

If UDP/IP or TCP/IP protocols are authorized, you can set up port ﬁltering, which allows you to control the protocol ports that are authorized to transport packets through the bridge. The default setting allows all protocol ports to

transport packets.

The bridge allows you to ﬁlter up to 100 protocol port numbers. Valid protocol port numbers range from 1 to 65535.
