When Host_1 attempts to send a packet to Host_2 for the first time, Host_1 issues an ARP request locally for the MAC address of Host_2. However, because Host_2 resides on a remote network, it does not respond. Instead, the FortiGate unit responds with its own MAC address. From that point, Host_1 adds the MAC address of the FortiGate unit to its ARP cache and the FortiGate unit will act as a proxy for Host_2.

In the above example, the private IP addresses between the two sites have been coordinated to protect against ambiguous routing (no two IP addresses are the same).

Setting up a configuration like this involves performing the following tasks at FortiGate_1 and FortiGate_2.

To enable IPSec VPN communication between two network hosts that coordinate the same private address space on physically separate networks, perform the following tasks at the local and remote FortiGate units:

1On both FortiGate units, define the gateway/tunnel on which to transmit VPN traffic to the remote location (see “Phase 1” on page 246 and “Phase 2” on page 250).

2On both FortiGate units, define the firewall encrypt policy that is needed to select and enable communication through the defined VPN gateway/tunnel (see “Adding firewall policies for IPSec VPN tunnels” on page 266).

3Using CLI commands to configure the local FortiGate unit, add VIP entries to define which IP addresses can be accessed at the remote end of the VPN tunnel (see “ipsec vip” on page 272). For example, to enable access to Host_2 on the HR network from Host_1 on the Finance network, enter the following CLI commands on FortiGate_1:

config vpn ipsec vip edit 1

set ip 192.168.12.2

set out-interface external

end

4Using CLI commands to configure the remote FortiGate unit, add VIP entries to define which IP addresses can be accessed at the local end of the VPN tunnel (see “ipsec vip” on page 272). For example, to enable access to Host_1 on the Finance network from Host_2 on the HR network, enter the following CLI commands on FortiGate_2:

config vpn ipsec vip edit 1

set ip 192.168.12.1

set out-interface external

end

The system provides centralized logging and reporting features, enabling users to gain valuable insights into their security posture and respond swiftly to incidents.

The 100A supports multiple deployment modes, including transparent, NAT, and route modes. This flexibility allows organizations to integrate the device into their existing network architecture with ease. The firewall's high throughput capabilities ensure that network performance remains unaffected, even under heavy load from multiple users and devices.

Another notable aspect of the Fortinet 100A is its support for various VPN technologies, including IPsec and SSL VPN. This feature facilitates secure remote access for employees, enabling them to connect to the corporate network safely, regardless of their location. As remote work continues to be a norm in many sectors, this capability is critical for maintaining productivity and security.

In addition to these features, the Fortinet 100A provides comprehensive web filtering capabilities, protecting users from harmful websites and inappropriate content. This protection is essential for organizations looking to maintain a secure and productive environment.

With its combination of powerful security features, flexible deployment options, and robust performance, the Fortinet 100A stands out as an ideal solution for organizations seeking to bolster their cybersecurity measures while ensuring seamless connectivity for users. As cyber threats continue to evolve, investing in a capable device like the FortiGate 100A is crucial for maintaining a secure network infrastructure.
