Wireless Functionality Allow the IEEE 802.11a, IEEE 802.11b and/or IEEE 802.11g wireless
clients to connect to the LAN-Cell wirelessly. Enable wireless security
(WEP, WPA(2), WPA(2)-PSK) and/or MAC filtering to protect your
wireless network.
Firmware Upgrade Download new firmware (when available) from the Proxicast web site
and use the web configurator, an FTP or a TFTP tool to put it on the
LAN-Cell.
Note: Only upload firmware for your specific model!
Configuration Backup &
Restoration
Make a copy of the LAN-Cell’s configuration. You can put it back on the
LAN-Cell later if you decide to revert back to an earlier configuration.
Network Address
Translation (NAT)
Each computer on your network must have its own unique IP address.
Use NAT to convert your public IP address(es) to multiple private IP
addresses for the computers on your network.
Port Forwarding If you have a server (mail or web server for example) on your network,
you can use this feature to let people access it from the Internet.
DHCP (Dynamic Host
Configuration Protocol)
Use this feature to have the LAN-Cell assign IP addresses, an IP default
gateway and DNS servers to computers on your network.
Dynamic DNS Support With Dynamic DNS (Domain Name System) support, you can use a
fixed URL, www.proxicast.com for example, with a dynamic IP address.
You must register for this service with a Dynamic DNS service provider.
IP Multicast IP multicast is used to send traffic to a specific group of computers. The
LAN-Cell supports versions 1 and 2 of IGMP (Internet Group
Management Protocol) used to join multicast groups (see RFC 2236).
IP Alias IP alias allows you to subdivide a physical network into logical networks
over the same Ethernet interface with the LAN-Cell itself as the gateway
for each subnet.
Time and Date Get the current time and date from an external server when you turn on
your LAN-Cell. You can also set the time manually. These dates and
times are then used in logs.
Logging and Tracing Use packet tracing and logs for troubleshooting. You can send logs from
the LAN-Cell to an external syslog server.
PPPoE PPPoE mimics a dial-up Internet access connection.
PPTP Encapsulation Point-to-Point Tunneling Protocol (PPTP) enables secure transfer of
data through a Virtual Private Network (VPN). The LAN-Cell supports
one PPTP connection at a time.
RoadRunner Support The LAN-Cell supports Time Warner’s RoadRunner Service in addition
to standard cable modem services.
Firewall You can configure firewall on the Proxicast Device for secure Internet
access. When the firewall is on, by default, all incoming traffic from the
Internet to your network is blocked unless it is initiated from your
network. This means that probes from the outside to your network are
not allowed, but you can safely browse the Internet and download files
for example.
IPSec VPN This allows you to establish a secure Virtual Private Network (VPN)
tunnel to connect with business partners and branch offices using data
encryption and the Internet without the expense of leased site-to-site
lines. The LAN-Cell VPN is based on the IPSec standard and is fully
interoperable with other IPSec-based VPN products.
