ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
network, a 1000-Mbps Gigabit Ethernet network, or a combination of these networks. All LAN
and WAN interfaces are autosensing and capable of full-duplex or half-duplex operation.
The VPN firewall incorporates Auto Uplink
TM
technology. Each Ethernet port automatically
senses whether the Ethernet cable plugged into the port should have a normal connection
such as to a computer or an uplink connection such as to a switch or hub. That port then
configures itself correctly. This feature eliminates the need for you to think about crossover
cables, as Auto Uplink accommodates either type of cable to make the right connection.
Extensive Protocol Support
The VPN firewall supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and
Routing Information Protocol (RIP). The VPN firewall provides the following protocol support:
I
P address sharing by NAT. The VPN firewall allows many networked computers to
share an Internet account using only a single IP address, which might be statically or
dynamically assigned by your Internet service provider (ISP). This technique, known as
Network Address Translation (NAT), allows the use of an inexpensive single-user ISP
account.
Automatic configuration of att
ached computers by DHCP. The VPN firewall
dynamically assigns network configuration information, including IP, gateway, and
Domain Name Server (DNS) addresses, to attached computers on the LAN using the
Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies
configuration of computers on your local network.
DNS proxy. Whe
n DHCP is enabled and no DNS addresses are specified, the VPN
firewall provides its own address as a DNS server to the attached computers. The firewall
obtains actual DNS addresses from the ISP during connection setup and forwards DNS
requests from the LAN.
PPP over Ethernet (PPP
oE). PPPoE is a protocol for connecting remote hosts to the
Internet over a DSL connection by simulating a dial-up connection.
Qualit
y of Service (QoS). The VPN firewall supports QoS, including traffic prioritization
and traffic classification with Type of Service (ToS) and Differentiated Services Code
Point (DSCP) marking.
L
ayer 2 Tunneling Protocol (L2TP). A tunneling protocol that is used to support virtual
private networks (VPNs).
Poi
nt to Point Tunneling Protocol (PPTP). Another tunneling protocol that is used to
support VPNs.
Easy Installation and Management
You can install, configure, and operate the VPN firewall within minutes after connecting it to
the network. The following features simplify installation and management tasks:
Browser-base
d management. Browser-based configuration allows you to easily
configure the VPN firewall from almost any type of operating system, such as Windows,
Macintosh, or Linux. Online help documentation is built into the browser-based web
management interface.
