Fortinet 50A User Manual

The FortiGate-50A 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.

Your FortiGate-50A is a dedicated easily managed security device that delivers a full 
suite of capabilities that include:

• application-level services such as virus protection and content filtering,
• 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-50A 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.
