I have 30 users in my network -- how can I use your gateway with only
four LAN ports?
The OfficeConnect Cable/DSL Gateway Family can support up to 253 users.
The four LAN ports on the OfficeConnect Cable/DSL Gateway can be
connected to additional switches and hubs to extend the network and the
number of users. Additional switches and hubs must be purchased
separately.
What is Network Address Translation?
Network Address Translation is a method of hiding a network so that all data
being passed out of the network appears to come from one computer. This
adds a level of security to your network and also allows great cost savings as
multiple computers can share one public address on the Internet.
