FortiGate-50R Installation and Configuration Guide
The FortiGate-50 Antivirus Firewall is an
easy-to-deploy and easy-to-administer
solution that delivers exceptional value
and performance for small office and
home office (SOHO) applications.
The FortiGate-50R is limited to a
maximum of 10 users.
Your FortiGate-50 is a dedicated easily managed security device that delivers a full
suite of capabilities that include:
•
application-level services such as virus protection, web content filtering, email
filtering, and network intrusion detection (NIDS).
•
network-level services such as firewall, intrusion detection, VPN, and traffic
shaping.
The FortiGate can operate in NAT/Route mode or Transparent mode.
In NAT/Route mode, the FortiGate-50 is installed as a privacy barrier between the
internal network and the Internet. The firewall provides network address translation
(NAT) to protect the internal private network. You can control whether firewall policies
run in NAT mode or route mode. NAT mode policies route allowed connections
between firewall interfaces, performing network address translation to hide addresses
on the protected internal networks. Route mode policies route allowed connections
between firewall interfaces without performing network address translation.
Transparent Mode provides firewall protection to a pre-existing network with public
addresses. The internal and external network interfaces of the FortiGate unit must be
in the same subnet and the FortiGate unit can be inserted into your network at any
point without the need to make any changes to your network.
