There are only 4 LAN ports on the Gateway. How are additional
computers connected?
You can expand the number of connections available on your LAN
by using hubs, switches and wireless access points connected to
the Gateway. 3Com wireless access points and OfficeConnect hubs
and switches provide a simple, reliable means of expanding your
network; contact your supplier for more information, or visit:

Does the Gateway support virtual private networks (VPNs)?
The Gateway supports VPN passthrough, which allows VPN clients
on the LAN to communicate with VPN hosts on the Internet. It is
also possible to set up VPN hosts on your LAN that clients
elsewhere on the Internet can connect to, but this is not a
recommended configuration.
