In this configuration the FortiGate unit could be added to this network to provide virus scanning, web content filtering, and other services to each VLAN.

System Network FortiGate IPv6 support Troubleshooting ARP Issues Address Resolution Protocol (ARP) traffic is vital to communication on a network and is enabled on FortiGate interfaces by default. Normally you want ARP packets to pass through the FortiGate unit, especially if it is sitting between a client and a server or between a client and a router. Duplicate ARP packets ARP traffic can cause problems, especially in Transparent mode where ARP packets arriving on one interface are sent to all other interfaces, including VLAN subinterfaces. Some Layer 2 switches become unstable when they detect the same MAC address originating on more than one switch interface or from more than one VLAN. This instability can occur if the Layer 2 switch does not maintain separate MAC address tables for each VLAN. Unstable switches may reset causing network traffic to slow down. ARP Forwarding One solution to this problem is to enable ARP forwarding. it can be enabled in the GUI or CLI. In the GUI, go to System > Config > Operation and select ARP Forwarding. For details on the CLI, see the FortiGate CLI Reference. When enabled, the Fortigate unit allows duplicate ARP packets resolving the previous delivery problems. However, this also opens up your network to potential hacking attempts that spoof packets. For more secure solutions, see the FortiGate VLANs and VDOMs Guide. FortiGate IPv6 support You can assign both an IPv4 and an IPv6 address to any interface on a FortiGate unit. The interface functions as two interfaces, one for IPv4-addressed packets and another for IPv6-addressed packets. FortiGate units support IPv6 routing, tunneling, firewall policies and IPSec VPN. You must use the Command Line Interface (CLI) to configure your FortiGate unit for IPv6 operation. IPv6 configuration is not supported in the web-based manager. See the FortiGate IPv6 Support Technical Note available from the Fortinet Knowledge Center. See the FortiGate CLI Reference for information on the following commands: FortiGate Version 3.0 MR5 Administration Guide 01-30005-0203-20070830 115
