NETWORK APPLICATIONS

Network Applications

The Barricade can be configured as a bridge for making a transparent connection to a remote site, or as a router for accessing the Internet. These applications are briefly described in the following sections.

Accessing a Remote Site

The Barricade can be configured to act as a transparent bridge between a local PC or LAN attached to the Ethernet port and a remote site across the ADSL link. Bridging can be used to make two separate networks appear as if they were part of the same physical network. When data enters the Ethernet port, its destination MAC address (physical address) is checked in the address database to see if it is located in the local segment (i.e., attached to the Barricade’s Ethernet port). If the destination address is not found, the frame is forwarded to the ADSL port and queued for output. If the destination address is found to belong to the local port, the frame is dropped or “filtered.” However, broadcast or multicast frames are always broadcast across the ADSL link.

The source MAC address of each frame is recorded into the address database only if it belongs to the local LAN segment. This information is then used to make subsequent decisions on frame forwarding. The address database can hold up to 128 unique MAC addresses. An entry in the address database will be discarded only if it has not been accessed for a period of time called the aging time. This is to ensure that correct forwarding decisions can still be made when a node is moved to another port, and to keep the table clean. The aging time has a default value of 10 minutes.

Note: Compared to routing, bridging generates more traffic for each network protocol, and uses more CPU time and system memory. Therefore, you should only bridge if you need to use protocols other than TCP/IP.
