Introduction
The SRXN3205 ProSafe Wireless-N VPN Firewall connects your wired local area network (LAN)
and your wireless LAN clients to the Internet (Wide Area Network) through an external broadband
access device such as a cable modem or DSL modem. As a complete security solution, the
SRXN3205 incorporates a powerful and flexible firewall to safeguard your networks, while
providing advanced IPsec and SSL VPN technologies for secure wired and wireless connections.
The ProSafe Wireless-N VPN Firewall
is the basic building block of a wireless LAN
infrastructure. It provides connectivity between Ethernet wired networks and radio-equipped
wireless notebook systems, desktop systems, print servers, and other devices.
The SRXN3205 provides wireless connectivity to multiple wireless network devices within a fixed
range or area of coverage—interacting with a wireless network interface card (NIC) via an
antenna. Typically, an individual in-building access point provides a maximum connectivity area
of about a 500 foot radius. Consequently, the ProSafe Wireless-N VPN Firewall can support a
small group of users in a range of several hundred feet. Most access points can handle between 10
to 30 users simultaneously.
The ProSafe Wireless-N VPN Firewall acts as a bridge between the wired LAN and wireless
clients. Connecting multiple VPN firewalls via a wired Ethernet backbone can further lengthen the
wireless network coverage. As a mobile computing device moves out of the range of one access
point, it moves into the range of another. As a result, wireless clients can freely roam from one
Access Point to another and still maintain seamless connection to the network.
The auto-sensing capability of the ProSafe Wireless-N VPN Firewall allows packet transmission at
up to 300 Mbps, or at reduced speeds to compensate for distance or electromagnetic interference.
The Gigabit Ethernet LAN ports and WAN port ensure extremely high data transfer speeds.
The SRXN3205 is a plug-and-play device that can be installed and configured within minutes.
