APPLICATIONS
Many advanced networking features are provided by the 3G Mobile
Wireless Router:
◆
Wired LAN — The 3G Mobile Wireless Router provides connectivity to wired
Ethernet devices, making it easy to create a network in small offices or homes.
Internet Access — This device supports Internet access through a WAN connection.
◆
Since many DSL providers use PPPoE, PPTP, or L2TP to establish communications with
end users, the 3G Mobile Wireless Router includes built-in clients for these protocols,
eliminating the need to install these services on your computer.
Shared IP Address — The 3G Mobile Wireless Router provides
◆
Internet access for up to 253 users using a single shared IP address
◆
account. Virtual Server — If you have a fixed IP address, you can set the
3G Mobile Wireless Router to act as a virtual host for network address translation.
Remote users access various services at your site using a static IP address. Then,
depending on the requested service (or port number), the 3G Mobile Wireless
Router can route the request to the appropriate server (at another internal IP
address). This secures your network from direct attack by hackers, and provides
more flexible management by allowing you to change internal IP addresses
without affecting outside access to your network.
◆ DMZ Host Support — Allows a networked computer to be fully exposed to the
Internet. This function is used when NAT and firewall security prevent an Internet
application from functioning correctly.
◆ Security — The 3G Mobile Wireless Router supports security features that deny
Internet access to specified users, or filter all requests for specific services. WPA
(Wi-Fi Protected Access) and MAC filtering provide security over the wireless
network.
◆ Virtual Private Network (VPN) Passthrough — The 3G Mobile
Wireless Router supports the passthrough of three of the most commonly used VPN
