Wired Ethernet LAN
You can easily connect any PC with an Ethernet LAN port to the SBG901 Ethernet connection.
Because the SBG901 Ethernet port supports
auto-MDIX, you can use straight-through or
cross-over cable to connect a hub, switch, or computer. Use category 5, or better, cabling for all
Ethernet connections.
Figure 6 Sample Ethernet to Computer Connection
The physical wiring arrangement has no connection to the logical network allocation of IP
addresses.
A wired Ethernet LAN with more than one computer requires one or more hubs , switches , or
routers . You can do the following:
•
Connect a hub or switch to the Ethernet port on the SBG901
•
Use Ethernet hubs, switches, or routers to connect up to 245 computers to the SBG901
A complete discussion of Ethernet cabling is beyond the scope of this document.
Security
The SBG901 provides the following:
•
A firewall to protect the SBG901 LAN from undesired attacks over the Internet
•
For wireless transmissions, data encryption and network access control
Network Address Translation (NAT) provides some security because the IP addresses of SBG901
LAN computers are not visible on the Internet.
